Doesn't take 2 pilots to do that.
Actually depending on the circumstances, it could well require two pilots talking to the ground crew.
A new pilot in their early line training, operating the sector as PF, (meaning they're the one talking to ground, whilst PNF talks to ATC), may have never been to Dublin before so unfamiliar with the airfield, unfamiliar with what was going on around them, confused by another aircraft seemingly in conflict and the ground crew stopping the push when they weren't expecting it.
Training captain would be very wise to take up the communication with pushback crew, thus leaving ATC ground un-responded to.
I'm not saying that was the case here, but it is easily a possibility, and BA have been recruiting like mad, they have their FPP scheme with pilots who are fresh out of CPL training, plus a load of direct-entry type-rated pilots onto short haul with maybe not much more than 500 hours. Lots of training going all the time there.
Thing is, unless you're actually on a runway at the time, if you're on the ground and not moving, then listening to ATC and replying promptly are usually not (as) critical, when compared to other things (such as talking to the ground crew who just stopped your pushback before an accident occurred).
