I've heard/read that. Makes no sense to me.
When I've done them in the car, I put slight jack pressure on the crank to seat the crank in the upper bearing. I'm one that uses plasti-gauge and set all bearings to .0015". The one exception is the rear main which I usually set a bit tighter. I also keep the shim packs equal thickness for one bearing. I usually have trouble peeling shims so I usually just sand them on a piece of glass.
Usually you'll find more clearance in the center main than the front or rear.
