I gathered that was the case. In situations where a radio might have dual antenna outputs, or a tuner has dual or triple outputs, IMO that is a better choice for switching antennas than coax switches.
One application where coax switches are nice is if you have two radios and only one external tuner, you can use the switch to switch between radios. But, again, DO NOT use those MFJ grounding switches for that. It will connect the center conductor of one radio to the RF ground system on the other and blow the front end out of it.
You might ask me how I know.
I once had this idea that I could use one of those MFJ grounding switches to switch from my radio to my antenna analyzer, use the analyzer to tune the antenna with the manual roller inductor tuner, then switch back to the radio and I'm all tuned up and ready to run. It was an excellent idea, no long tuning carriers on the air trying to tweak the roller inductor and twin capacitors in the tuner. Except for one problem. When I keyed the transmitter it blew that antenna analyzer all to smithereens and it was non-functional after that. That was the point where I decided the anvil and maul thing was the best fix for those MFJ grounding switches.
