The switches will work in either direction... two input to one out, or one input to two out.

Not anymore.
I have my HF rig and 11 meter radio on on side of the antenna switch. On the other side, I have the g5rv and the antron 99. depending on where I have the switch it swaps them out. so, if I am on 10 meters on the hf rig, I can use the antron because it works better. however, if I am on another band, I can switch to the g5rv. I can do all of this without having to disconnect and reconnect anything.
