Hi,

?Developer`ClearCache

"ClearCache[ ] clears internal caches of stored results."

Mathematica save some results for speed. You will see this 
if you call FullSimplify[] two times on a complicated expression,
the second call is usual much faster because the simplifications
are cached. ClearCache[] remove *these* results, but it leaves
the definitions of your session untouched. So, ClearCache[]
restore you Mathematica session *not* to the original state.

Regards
  Jens
