I feel my future self will disown any gratuitous 'cleverness', so for me personally, a comment on some clever code is more likely to be an admission to Future Self of being too much clever, and not enough smart :-)
Also, it's a little like explaining the punch line of a joke. One either feels that the joke has failed, or else being condescending to explain it. Another form of imposter syndrome
