I recreated this problem, did some research, and this is what I found.
The RFC on AURP(1504) states this:
"An exterior router connected to multiple tunnels functions logically as
though it were two or more exterior routers connected to the same
AppleTalk network, with each exterior router connected to a different
tunnel."
So this IS a split horizon issue...a router will not advertise Exterior
Routes it learns on one tunnel out the other tunnel. It views the AURP
tunnels as the same network.
The solution:
Full AURP Tunnel Mesh
Create a tunnel on each spoke pointing to the other spoke. After
implementing this spoke to spoke route table convergence was achieved.
