Why does replace-regexp backwards work so differently?

C-u - M-x replace-regexp \w+

The - prefix arg replaces backwards but it hits one char at a time, as if the plus sign weren't there. The same replacement forwards (without the prefix arg) does hit one word at a time. What's going on, @[email protected]?

Yes, I got that, that wasn't the weird part. The weird part is why the matcher is searching char-by-char backwards in the first place as opposed to skipping match-by-match.

I'll use "\b\w+", that seems to work well. \W\w+ was not good since it caught the spaces.

(Thanks for your patient repeated replies, BTW, I don't mean to come across as ungrateful.)
