There are 2 information processing errors with the Moses Illusion, instead of just the one of identity. The given answer is that it wasn't Moses. But as well as that, it wasn't "2 of each kind" either:

"Take with you seven pairs of every kind of clean animal, a male and its mate, and one pair of every kind of unclean animal, a male and its mate, and also seven pairs of every kind of bird, male and female, to keep their various kinds alive throughout the earth." -- Genesis 7:2-3

For whatever reason we are taught as children that it was 2 of every animal, but really it was 1 or 7 pairs, depending on whether they were clean, not clean, or birds. The song singing "2 by 2" is essentially correct, but deciding that means there were only 2 sheep is not correct. Spoiler: There were 14 sheep.

That makes 2 information processing errors. In terms of coding, it's not easy to tell what errors the identity issue would cause since that would be implementation specific. But the second issue would clearly trigger a buffer overflow.
