Anyone know if an mvrf can be "leaked" across several vrfs?

ip vrf mvpn-cus1
 rd 10.0.0.1:201
 route-target export 65000:201
 route-target import 65000:201
 route-target import 65000:202
 mdt default 239.1.1.1
!
ip vrf mvpn-cus2
 rd 10.0.0.1:202
 route-target export 65000:202
 route-target import 65000:202
 route-target import 65000:201
 mdt default 239.1.1.1
!

Cisco doc says:

"When configuring the default MDT, note the following information:
•The group_address is the multicast IPv4 address of the default MDT
group. This address serves as an identifier for the MVRF community,
because all provider-edge (PE) routers configured with this same group
address become members of the group, which allows them to receive the
PIM control messages and multicast traffic that are sent by other
members of the group.
•This same default MDT must be configured on each PE router to enable
the PE routers to receive multicast traffic for this particular MVRF."

Which makes me think it might work...
