Yes, this is intended behaviour specified in IPv4 routing. I don't remember the
RFC, though, but simple IPv4 routing is based on destination address only, not
on source address. As such, if you have 2 netifs on the same subnet, the simple
routing algorithm will always send packets to the first match, which is what
you observed.
