I think that Airbus did not have any kind of official information about the accident prior to issuing that statement. In other words, they could not issue a serious statement without the conclusion of the investigation...About the TL above idle at flare: I can’t really see that happening! Would make more sense to me a "Thrust lever fault" at low altitude (the warning might have been inhibited due to landing proximity).
At TAM, some aircrafts are equipped with a LIP (lift improvement package), witch changes the airplane handling at landing. It is common to keep the engines at CLB detent until 20 or 15 feet on this kind of aircraft (similar to a 737 Efis flare), or you might have a very hard landing.
But MBK did not have the LIP, so...
