I'v'e been wondering that too. From about move 109 to 125, he had sente several times, or could have taken small losses by tenuking to save his group. After 126, it looks dead.
Particularly noteworthy was move 111, with which he killed Zen's upper right. But his net profit there looks smaller than the loss of his dead group. So my conclusion is that, yes, he misread: he thought that he could live after 126 - probably by connecting to the northeast.
Also move 123 looks smaller than the dead group, so he must have thought that he could live.
If he lost on a misread, then my bet is still that he will win. When he does not misread, the game is lopsided.
