I notice it is using a new field in the update and that it is tied to the label block of the PE so it might be that a single update can now wipe all MAC address routes for a PE rather than having to send a route withdrawal for every MAC address which could take some time?

It seems also "mac-flush" is now available with BGP based VPLS - before that was only supposed to work with LDP based.
