ya, they can backfire for sure. Just look at guile, his auto correct flash kicks mostly end up fucking him over then ever helping him.
auto-correct moves aren't the end of the world, but I personally don't like them. Seen and been on the receiving end of too many auto-correct moves that I just hate the concept. I mean, for christs sake, even Ultras can auto correct.
oh no, my only choice is safe jump (if i can) after I knock you down because any cross up attempt will just be auto-corrected by the opposing player.
also,
auto guard = lame, players don't like it
auto tech throw = lame, players don't like it
yet
auto correct = awesome, players love it
something is wrong with that imo.
