Well... I don't really think that they would. It just doesn't make sense on a biological level because of what I stated before about the loci.
Tremper x bell produces wild types because these alleles are not at the same loci. Because they are not at the same loci, you get wild type x tremper at one locus and wild type x bell at another locus, producing a gecko that is heterozygous for both tremper and bell.
I think what must have been happening is that you breed a bell and tremper, you get normals het bell and tremper. You breed those together, you only have a 6.25% chance of producing one that is homozygous for both. You have a 12.5% chance of producing either a bell het tremper or tremper het bell and a 25% chance of producing a normal het tremper and bell.
So I think what's happening is that it is indeed possible to have one that expresses both (It only makes sense genetically for this to be the case), but you're pretty unlikely to produce one.
discoverlight: I don't know what strain he is. I'm not convinced you can tell with every gecko. I see now that there are some that are pretty obvious, but the lighter colored ones seem harder to identify.

For a little background:
A locus (plural loci) is a location on a chromosome. So each allele has its own location (locus) on the chromosome.
So let's take Locus A and Locus B. Locus A is where the allele coding for tremper albino is (two chromosomes, so two alleles total at the same locus) and Locus B is where the allele coding for bell albino is.
In a homozygous tremper albino, Locus A is tremper x tremper and Locus B is wild type x wild type. In a homozygous bell albino, Locus A is wild type x wild type and Locus B is bell x bell.
So when you breed a homo bell and homo tremper, the tremper parent has a tremper allele at Locus A to donate and a wild type allele at Locus B. The bell parent has a wild type allele at Locus A and a bell allele at Locus B.
Because each only has these alleles to donate to the offspring, the offspring will get wild type x tremper at locus A (one allele from each parent) and wild type x bell at Locus B (also one from each parent).
I hope this clears up my thought process a little. It's not like I have the leopard gecko genome all mapped and handy or anything, but this is what makes sense to me from my studies on genetics (I am a molecular biology student).

The gecko looks like an albino (strain unknown) that has lost its beige and only retains the yellow and white. I have one like that as well.

None of the albino strains are compatible. Your gecko is a strain of albino, but there is no way to know which one without test breeding. These bubblegums are not a good thing and almost every breeder will tell you to stay away from them. No albino strains should be bred together on purpose. When you breed a bell x tremper, you will get all normal babies that are het for bell and tremper. When you breed those together, you will get albinos, but you won't be able to tell which ones are tremper and which are bells. There is a pinned post here on muddy waters that explains a lot of this.

I have this pinned in this subforum, but here is a link again. The bottom section talks about ethics with breeding and mentions about the albino strains. Hope that helps, too.

To clear up some obvious confusion-
Yes, the three albinos are incompatible, and therefore an animal *could* be homozygous for multiple types.
HOWEVER, all three types of albinism in leos are Tyrosinase positive, and therefore even if an animal were homozygous for two or more types of albino, it would look no different than an animal homozygous for only one type of albino.
Bubblegum is a BS group of geckos from breeders that took shortcuts. That's it.
Your animal in question, yes, is albino. But thankfully, as you've already said, it should not be bred.
The only thing you'll get from crossing albinos is a ruined reputation/credibility, and an abolished sales base. All you're accomplishing is breaking a molecular pathway at multiple points, which may lead to severe developmental defects. So if you truly care about the health of the animals, it shouldn't be an possibility that ever crosses your mind.
