"Low Band "apply question

No matter whether
it be second or third gear you are in as you come out of the water, you should start to deaccelerate
engine or do a power burnout directly to the staging line being sure tires never grab dry pavement.
.

I don't understand this last part, and I've read it before.

Hell what are you supposed to do if the tires are broke loose ON DRY PAVEMENT in 2nd or 3rd gear?????
