Yes, it has to do with MPLS VPNs and VRFs. The actual purpose of the global option for the ip route command allows for recursive lookup into the global table for the next hop of the VRF route. For instance, if you wanted to allow an exit point from a VRF to the Internet you could add a default route in the vrf with the global keyword to the next hop of a non-VPN router. This will allow the router configured with the default route to strip the VPN label and forward using the global routing table thus creating an exit point from the VPN. It gets a little more tricky when creating an entry point into the VPN considering security, network design, etc...
