Ed Haywood
En-Route
I'm not disagreeing with Ed, but...
As a low-time (~200 hours) pilot, even I am not confused by these instructions. The first part - "Remain this frequency" is as clear as it gets. The second could be confusing if they aren't familiar with the taxiways. But, in that case, the next transmission from the aircrew would be (on the same frequency since they followed instructions to 'remain this frequency') to ask for directions to parking...
Again, not really disagreeing, but I just don't see how it would be an issue if the crew just followed the initial instruction to remain this frequency.
Of course you are not confused by these instructions. You are reading them in your living room with no distractions and plenty of plenty of time to think about the meaning, not hearing them while turning off a runway and saying to yourself "cross line, change freq, contact ground, ask for taxi".
