Bumpthump - at TDP, if using the AW confined area profile, the yaw offset to provide sight of the LS is taken out as the nose is pushed forwards to gain speed. thereafter it is as Shytorque says
In the instance of the 169 variable TDP procedure it’s not necessary because flown correctly you should have the pad (and reject area) in full view between the pedals through the chin window all the way up to TDP. You aren’t needing a good visual picture of what is hidden by the instrument panel. Offsetting could actually lead to a condition where you have the wrong sight picture through the pedals. There is nothing in the video to suggest he did offset the nose left during the initial manoeuvre - it’s looks perfectly straight.
AW169 QRH - The G&E H/H variable TDP consists of a slow (less than 300 fpm) climb above the take off surface maintaining the centre of the take off surface in sight between the yaw pedals up to TDP. The pilot then rotates to transition to forward flight and into the climb
