That's a good point I haven't considered that and now it makes sense.

However in my setup I have a CE connected to two PEs and I use per PE per VRF RDs so prefix received over MP-iBGP and prefix received over eBGP should be considered as two unique prefixes rather than candidates for best path selection.
Ooooh and that answers my question geez I'm stupid :) what a bummer!
Sorry folks for wasting your time.

Thank you very much Oliver.
