We may have all fluffed it at little once or twice as might ATC (starting a landing clearance with a wind as an aircraft vacates)
That's not a fluff, that's a good use of RT time, and an SOP for me.
BTW line up on the runway and then tell me to stand by you had better have a really good reason when in Hi-intensity runway ops. Not that the ATCO covered themselves in glory according to the truncated recording but the BA would not have departed for me and vacated followed by an MOR.
