The ASA should be smart enough to avoid using the same ip address at the very same moment, after the ip address has been released by any vpn client, it has the "reuse-delay" parameter to find out how long it have to wait to use it after it has been released:

I haven't tested for address conflicts but know ASA installs route to ip assigned to VPN user from local pool with bitmask 32 and outgoing interface as outside (if users connect to outside). So logically would be to think more specific route to VPN user wins over network address with less bits in mask (configured say on LAN interface in ASA).
