MIL and mom do correspond occasionally - send each other photos of the grandkids if one gets a particularly good shot, holiday cards, flowers for funerals (e.g., when my grandmother died). They are pleasant to each other when they see each other but they have nothing in common besides the grandchildren
I don't know, it sounds like they interact a lot for not getting along. My mother and MIL do not communicate at all.
