I suppose it's like the case with the Visored in Fake Karakura Town. "The enemy of my enemy is my friend".

Grimmjow have probably witnessed how the Wandenreich mercilessly slaughter Hollows and Arrancar, he's probably helping Kisuke's group just to exterminate the Wandenreich and the threat they pose to Hueco Mundo.

And he might want a rematch with Ichigo after the war.
