Good questions. I think if you are fishing with 2 rods at the same time -- like trolling with 2 rods from the boat -- or you have two rods and are fishing from the bank and are all by yourself, it would apply.

However, if you carry two rods, only fish with one at a time, I would argue that it does not apply (sometimes I'll carry both a spey rod and a single handed rod -- or a 4 wt and a 6wt --but only fish with one of them at a time). Hell, maybe Joan Wulff can cast with two rods at the same time but I can't. Otherwise, they could site you for just driving up to the beach or boat launch, etc. with maybe 4 rods in your car/possession but not using them.
