The T7 undercarriage has rear steerable wheels which will castor to maintain airplane ground track upon touchdown when the aircraft nose is not fully aligned with the runway.
That's news to me... I do know that the 777 has the ability to allow the 3rd pair of wheels to unlock during taxiing to avoid tyre scrubbing in tight radius turns. If these are not locked straight before takeoff (an automatic function) it will generate a config warning.
Personally, I find the triple very good in crosswinds. Up to 25kts I use wing down and over that I combine wing down with either landing with the rest of the drift still on, especially if wet, or an extra little decrab close to touchdown.
