Yes I think that was a similar deal for Oxford Road on analogue only, and well into the overscan area so wouldn't have been seen on domestic sets.
I think there was some speculation (possibly originating with me, I can't remember) that it was a visual equivalent of the VBI ident used to signal that Manchester had opted out, used to switch the IoM transmitters to NW from NE.
