I think the problem here is that black ends up with a protected passed pawn and in a piece-less ending, a protected passed pawn is generally better than a simple distant majority. The opponent can win the isolated passer while the protected passer sticks. My evaluation here is -.44 (good for black) after e6. Whether it will win that or not is a guess. Ulf is very strong of course... I've played him several games as well...
