PIM shouldn't be needed; Multicast packets should flow fine within the same IP Subnet (VLAN) assuming there is no problems at L2. PIM is needed when doing multicast between IP subnets (VLANs).
You probably were running into a HSRP Virtual MAC address versus switch CAM table issue. Since the vMAC is same for both routers switch might have issues keeping track of where this MAC is. Configuring HSRP to use bia (burned in address) fixes this problem.
Perhaps enabling PIM cleared something up somewhere. Does HSRP break when disabling PIM or continue to work?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
