If the LAN side of the CE's maintained the VRF separation then of course, you would expect no problems with that.
if the CE's have a GRT for LAN side and if those two prefixes were leaked into that GRT, then I guess GRT would end up with the two routes from different sources, the longest prefix rule would mean that anything falling into the /29 would still go via vrf B and everything else would go via vrf A.
so it would mean that legitimate traffic for 172.16.10.0/29 meant for destinations on VRF A would instead be sent via VRF B, while legitimate traffic for the 172.16.10.0/29 for destinations on VRF B would always get there ok. Basically, the longest prefix routing rule would come into play and break /29 for VRF A.
I think the same would go for a non VRF aware CE which is receiving the two prefixes from upstream PE's.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
