Why not? He's won five times so far.
Hulk has beaten Thor five times? He has certainly shown he was more savage in his attacks, more willing to kill, but in all of Hulk-Thor history, never has the Hulk been shown to physically over power Thor. Even in the story you provided, Hulk practically ambushed Thor after they crossed over to this dimension after having been soundly beaten in the other dimension. In all the fights (save one), what we do see is a Thor who repeatedly gains the advantage but fails to strike the killing blow. The one exception being the story where Thor decided that they were too closely matched physically and had no choice but to kill the Hulk in order to win, and, of course, he did so quite easily in the end.
On the other hand, we see what Thor can really do in the Blood and Thunder series when with no "belt of strength" or other augmentation, solely under his own power, he takes people as strong or stronger than the Hulk (like BRB, Silver Surfer, Maxam and Power Gem boosted Drax) and treats them with utter disdain.
