For the guy who said he believed rolling was an RAF term; It is, but means something entirely different; it means you are bashing the circuit & this time around you are landing & taking off again without stopping. I'm pretty sure thats not what the crews here mean.
I don't think there is any harm in the call as long as the correct readback has been given back & it's just tagged quickly onto the end to show you are aware of the one about to land on top of you.
