Sounds like a bug (or bad design).
If the watches (or anything) did this deliberately, you would not have to turn-off broadcasting (like the OP describes having to do).
There's an icon that is displayed when broadcasting. It would be bad if that icon is displayed when broadcasting is turned-off.
It's arguably a bad design to turn this off even with turning-off the icon because it's easy to forget to turn it on.
If it's using ANT+, I don't think it would work this way (ANT+ usually has no idea it's being received).
(I can't find anything that says the watches behave like this.)
