You're right I have both:
However they're in the above order in the global handlers section so I think it may be first wins since I haven't had the fencing stay but the snapshot did?
So this fixed it in global:
after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh; /usr/lib/drbd/unsnapshot-resync-target-lvm.sh";
