SPE 2K-FA can TX power end up going out the S02R port

Does anybody happen to know if it is possible for radio TX power to end up going out the SO2R port on the SPE-2K-FA amp?

I have two radios:   Input1 is Flex6600, Input 2 is Yaesu FT-991A.   The amp seems to auto switch inputs exactly like I want.  But I'd like to put a receive antenna into the SO2R port, seems it is designed for this, but there would be some devices in parallel on that same antenna that would not like TX power.

Any one know?

Put a watt meter on it and see.

Yes, if you transmit with both radios at the same time the first one the amp detects will be amplified and directed to the selected antenna for that band while the second will be routed to the SO2R antenna connector.

The drawing shows relay in normal "not on state" puts input two to both ant 2 and SO2R. I put a small dummy load on unused ports myself.
