Is the Homorphus Charm performed on Harry by Gideroy legit ?

First off, I just posted my brief off topic satire 
THE POLITICALLY CORRECT HARRY POTTER 
which can be found at 

http://groups.yahoo.com/group/HPFGU-OTChatter/message/18850

all comments positively or not would be greatly appreciated.

Now for the question at hand - on pages 161-162 of COS,
Gilderoy Lockhart performs a demo on Harry before the
DADA class of the Homorphus charm he allegedly did in
defeating the Wagga Wagga werewolf.

Gilderoy does say that "another village will remember
me forever as the hero who delivered them from the
monthly terror of werewolf attacks" implying that he
did it (or lied about it) more than once.

Any thoughts as to whether this spell is bogus or
legit ?
thanks
