I know a bridge starts out with the MAC of the first port you add to
it. If you remove that port it will choose the MAC of another member,
but I have no clue how it makes the selection.
What you could do to ensure a unique MAC on the bridge is create an
EoIP interface and add that interface to the bridge before adding the
VPLS interfaces. The EoIP interface is just a useless stub, but it
has an algorithmically generated MAC address and you can override it.

Follow up, I found out that is correct with VPLS.
However, I had two bridges on a router each containing a separate
VPLS endpoint/interface in them that had the same MAC address.
The MikroTik bridge assumes the MAC address of one of the member
ports, not sure how it figures out which port MAC address to use.
In one case it had select the VPLS tunnel MAC in both bridges for the
two spate VPLS endpoints, that happened to have the same MAC.
So I ended up with two bridges on the router with the same MAC
address.
This caused a bridge loop, or at least a notification of a bridge
loop my having the same MAC address show up in cycle.
Very interesting.

I noticed on Mikrotik you can assign/change a MAC address to a VPLS
interface.
Is that MAC address supposed to be always unique?
Several of mine on any given device are using the same MAC address.
