The TCAS did not tell them to go around, but the TCAS display DID show the aircraft going around...

for for read "...indicating that he had commenced..." and it should make sense. I think.

TCAS low down
 
OK that is useful, I thought the whole idea was that TCAS would disable its display from showing anything under a set height, and also disable itself while an aircraft is wheels on ground to avoid confusion - hence the surprise that a low aircraft about to go around was showing at all.

The only part of the TCAS system that is supperessed when at low altitudes is the RA's. The rest of the system works even on the ground. We often use it to monitor the approach before entering the runway.

Typical. Bloody Scotsmen driving minibusses getting in the way of proper aeroplanes doing proper work! ;) (No, it wasn't me driving the 301).

PS At normal landing weight, the A340's Vapp would have been about 135-140kts, and the IAS inside 4D would have been about 145, so long as groundspeed mini wasn't a factor. So the overtake would have been about 20-25kts. If it was a -600, add 5 kts or so.

Shame it wasn't you, matey.... from what I hear you can do with the practice ;)

Just blame ATC. I do. Then I get slapped. But I do.

Beer soon, hopefully? All the best.
