Right before King of the Ring 2001, they beat Jericho and Benoit for the titles with Austin's help. McMahon wasn't happy with Austin after the match.
They, I believe, added the Dudleyz v. Kane/Spike to the PPV... I don't think that match was on the show previously, I think they added it on Heat.

At least in that situation, Jericho and Benoit were in a different match for the PPV, so that way they got to have a tag title match too. In this case they just switched the tag titles on the show before the PPV. Why? I don't get it.
