...or maybe I just don't completely understand how this works.
The context to the question is that I am wondering if I have to use 2W or 5W setting in order to communicate with blister packs, or the better power setting in general (since apparently, 5W transmitters are illegal for public in Canada).

This would happen even if the tones were different. PL tone is not a secret Chanel or security it only tells your radio when to turn the speaker on.
What your describing if I understand it is.
Team A radio on channel A, PL A
Team B radio on channel A, PL F
If either team A or B are transmitting and receiving clearly then team B transmits one of two two things happen. Either one of the teams radios over power the other transmission or what typically happens is they mess both transmissions up by QRF, or talk over.
PL tones are only a way to break squelch and not sub channel security of any means.
