Is that always true? I know I hear this pattern sometimes, but I thought
it wasn't necessarily true.

Not i my experience. I have actually heard the controller's transmission stop
midway thru as he was talking to an airplane on another freq....switched to the
freq he was talking to the other airplane on and hear him finish his
transmission.

Yeah, seems like I've had a similar experience -- heard another
aircraft told "change to my frequency blah blah point blah", didn't
hear any other ATC transmissions to that plane, wanted to know 'cuz
I was heading for that airport, put that freq up on #2 comm and heard
'em.

Most of the time they will broadcast on all the freqs they are
working, but not always.

I wonder if it's some sort of hardware patch thing, where normally
they just route all the transmitters to one place and broadcast on
all the freqs they're working, but if there's a glitch of some kind
they wind up having to manually switch to work around it.

Not that any portion of our ATC system would ever experience any
kind of glitch that their tech. folks have to patch around or
anything like that....
