This is a "normal" behavior that you can also see with physical router. If multiple routes to the same destination are received, they only place the one with the highest priority in their routing table.
On a high level this is due to the decoupling of routing information base (rib) and forwarding information base (fib). The rib takes care of the path selection, e.g. calculates the best path for each known destination (based on different rules and algorithms) and places only this one in the fib, so if there is a packet received that needs to be forwarded the router only needs to look up the next hop in the fib and forwards the packet without the need to calculate the best path every time.
I guess it's just the same for TGW route table, I hope someone here can confirm that :-)
