Excelent post Rainboe.
There are two golden rules when it comes to approach and landing.
1) Once a go-around has been initiated, don't revoke your decision.
2) Once thrust reversers have been deployed, go-around is not an option anymore.
The one reverser in transition and the other at g/a thrust can definitely explain the large change of ground track in such a short distance.
Initially it reminded me the Girona accident. A lot. It was then a suspicion that reversers had been deployed and a go-around was attempted afterwards. We know now that the collapsed on landing nose gear, broke the thrust control cables, causing the left engine to advance to full thrust !
There is always a reason for such a deviation from the centreline or extended centreline. Sometimes it is obvious, some other times...not. We'll see.
