True, although, quoting the site you give:

"but his work will need to survive two years of systematic scrutiny after publication, before the Clay Mathematics Institute can deem the conjecture to have been solved."

If his proof was in 2003, and we are in 2005, this scrutiny shoudl ahve been finished by now. Maybe the site isn't updated, maybe look in the oficial web page of the prizes we can see if it's accepted to be solved.
