He probably meant iSCSI devices, not ASM disk groups. That's true since iSCSI stands for Internet SCSI, i.e. encapsulates SCSI protocol so you can run it over your network. The devices then look as any other SCSI device to the OS.
The requirement you quoted is from SnapManager and that might be relevant -- perhaps SnapManager was coded with some assumptions about asmlib presented in the system? It certainly should not be a generic requirement.
