ip igmp immediate-leave group-list 1

Hello,

Task says:
"interface F0/0 of R1 should be configured such that it stops forwarding
multicast traffic for all groups immediately upon receipt of an IGMPv2 group
leave message."

Workbook solution is:
access list 1 permit 224.0.0.0 15.255.255.255
int f0/0
 ip igmp immediate-leave group-list 1

My question is regarding access list 1. Would the following access list be
OK?
 
access list 1 permit any

After all there is no igmp immediate leave for anything else than multicast
so why bother with multicast address range here ?
 
Thanks
