eth0.1 and eth0.2 are entirely separate interfaces. The behaviour is
exactly the same whether you use two VLAN's or two physical interfaces.

Imagine replacing eth0.1 with eth1 and eth0.2 with eth2. If a certain
MAC address is learned on eth1, it would be wrong to send packets
destined for that MAC address through eth2. That's pretty much the point
of bridging.
