No I don't think that's a problem either, because if there were bridges between two RBridges
R1 and R2, when R1 transmits into the "layer 2 cloud" (a bunch of
links connected by bridges) that connects R1 and R2, the header
that bridges between R1 and R2
would see would be source=R1 and destination=R2 (the "outer header"), so having packets from
an ultimate source S in the inner frame that appear from multiple directions won't confuse
the inner bridges.
