Eh????
If you give ATC something to act on, of course they cover their backs...ie call the fire brigade to be on standby. Wouldn't you if some foreign operator comes to your place telling you it's going to be a bit smokey, but it's ok mate.
TCX, pleeease tell me why an engine going to smoke after touchdown??? That's not normal.
I agree that, with the benefit of training, we all know that there's a cockpit procedure for tailpipe fires, but it's easy to see the chain of mis- communication that lead to a guy being primed to fight a fire. I doubt it will be the last time.
