The sword-blocking in Jodo can (and perhaps should) all be done with movement lateral to the strike. This produces kuzushi and/or seme in addition to stopping the cut. Squarely catching the ha is probably not a functional tactic.
It is proper to do it however your teacher instructs, understanding that basic technique may be for timing and call for direct blocking, which may be modified to a moving block later.
