I belive, from reading though some threads, that if someone uses the:
/me means this
function, and then another user qoutes that original person, then the name changes.
i.e. 'biggles' uses the function to say "* biggles likes pie "; 'Snail face' then quotes 'biggles' but it changes to read "* Snail face likes pie "
I hope that all makes sense!
