In GSE there is no notion of globally unique edge site prefixes. When a host resolves an address for another host in an external site and sends a packet to it, that packet has (one of) the RG(s) of that external site in it's destination address field. GSE is just a very clever form of NAT. NAT in general is a separation scheme that does not require the mapping you describe above.
