Everybody seems to have their own view of these verses. For me, there is a third verse, or should be, in Deuteronomy. There Moses is giving his valedictorian speech, repeating his greatest moments, and most of the laws. Somehow he ignores, forgets, or rescinds these two statements of Leviticus, by not mentioning them, though mentioning most, if not all of the other taboos, of sexuality.

If one assumes, there should have been a third, then going backward, the first included an abomination, the second excluded it, and third is non-existent. Perhaps all that is going on here, is Moses going through a state of confusion, any one having regular sessions with God is likely to do so, and eventually just drops the issue completely. What is left is unintelligible which may more or less mirror Moses’ understanding.
