Let's discuss this. The penalty is 10 yards (basic spot) and a loss of down, if not in conflict with other rules. Then, there is an exception for a scrimmage kick, not in play here. The only potential conflict I can see by not having a loss of down is the fact that the basic spot on a kick play is the previous spot. But is that really a conflict?
To me, a conflict on this comes into play when it is Team B that commits the foul. There can never be a loss of down on a Team B foul. Right? I won't say always, but there could almost always be one on Team A, right?
