90% speculation in this thread.
Hogan scored a huge deal from WWE, and agreed to put over The Rock. He suggests they close the show as he felt "they had drawn the crowd" - but McMahon and specifically Triple H refuse to put the WWE Title match in a secondary role.
This is true, and there's a footage of HHH contradicts himself in his 2002 DVD "The Game" and the 2011 WM DVD, in one video he said that the title is the most important thing and should be last. In the other he says that HE told WWE that Rock/Hogan should be last but THEY wanted him to close the show. Completely hypocritical and especially after WM26 when the title wasn't the last match.
Hogan was right about a heel ending WM, the crowd exploded when Hogan won and he send them home happy, like you should do at WM. As for the belt, he just put over his title match, nobody was going to see what he said about the WWF title anyway because it was a PC in Japan, and he's putting over their title to make it bigger. Simple and smart marketing to draw crowd.
