That should not be the case.. Have you tested this without VLAN setup or
external bridging in place? ap_isolate=1 is only disabling the internal
bridging within mac80211. It would still be possible for something
outside mac80211 to do bridging between netdevs.

I don't see why this would be any different between WPA2-Personal and
WPA2-Enterprise, i.e., the difference is much more likely to be
somewhere in the VLAN and/or bridging configuration. If you bridge
together multiple interface or allow bridge to forward frames back to
the same port, mac80211 won't be preventing those externally forwarded
frames from getting through to another station.
