NFHS Rules 2012-13 Rulebook page 62 PK Situations

I have wondered why, in the five situations presented, when an attacking team encroaches, in four of the situations the rules give the ball to the defense in some form.
The exception is when the attacking team scores: rules dictate a rekick.
Would it not be cleaner to have the same outcome for all five situations? i.e.
the ball goes to the defense.
The only rationale I can think of is that with a rekick you and the rules are not penalizing the encroaching team twice by both taking the goal away AND giving the opponent the ball. In the ensuing four situations where the kick is missed or held by the GK or goes off the GK and out of play...the encroaching team has penalized itself by missing the goal...so you and the rules are only really penalizing them once by taking the goal away but giving them a rekick.
Thoughts?
