The police have been putting this advice out for a while now. About 2 years ago they had a bus stop picture campaign about stopping to let emergency services pass rather than changing lane that looked similar to the give room to cyclists signs.
I think the very half assed way they went about changing the advice they are putting out has just made more confusion, 50% will move left and 50% will stay in lane jamming the entire road.
