So my question is should the two cases really be treated differently in practice?

Well, I was conflating the two, it seems. The violations I've called have all involved the actual painted restraining line. I can see the distinction, though, in that the painted line should be easier for everyone to adhere to.

I just noticed that the case play does not reference a rule that grants the authority used in the case play. Is there one, or is the one of those instances where the rules have been amended via a case play?
