Plus you still have a brutal attack with two rooks, involving mate threats, and probably slightly better ability to pick off pawns than White's lone queen.

The only thing I can see in common between these two positions is that, in both of them, White is forced to make a move that loses material. In the first position, it's 36.Rf3. In the second, it's 41.Rxf4. I would doubt that Chezzz has a specific problem with this, but I would need to see the PV for 32...Qa2 to verify this theory. I did notice that, in the second position, Chezzz likes 39...Nc2, which only wins the b4 pawn, instead of 39...Ne2 with wins the exchange as mentioned above. That's all this patzer is able to see with CM9000 and a slow machine.... sorry.... :-) jm
