To use the cam locking tools he has.

The primary reason is to have all of the pistons slightly down in their bores. This prevents bending of the valves if a piston is fully up and cam is turned.
This step of having pistons down in their bores is also very important when installing heads / cams on most any other engine even if it is times at TDC.
