De-crab after touchdown
I will speak from many years of experience over a wide range of large airframes. Lots of Boeing, 727 through the74, and some AB, 300 series. When touching down on a wet runway the airframe naturally de-crabs. This is set up by the increasing friction, or side load on the wheels and gear. Many companies also require the nose gear to be on the runway prior to entering reverse thrust. (This extra contact and vector will allow the direction of the rolling airframe to remain closer to runway alignment than with only the main gear in contact with the surface.) If you watch the Boeing video referenced earlier, you will see the airframe de-crab as it continues the roll out. Now some rudder input may be applied and with some aircraft includes the nose wheel steering to some degree. The mass the of airframe wants to continue down the centerline and not at the crab angle.
Just prior to touchdown the crab angle keep the airframe s lined with the runway, after touch down the crab angle is reduced to zero very shortly after touch down by the friction and vector mass of the airframe.
Not sure if this helps.
