This IS a problem - consider this scenario (this is how it happened to
me...)
I was listening to 30 meter CW (Main Rcvr) and also listening to a 60
meter channel (USB) on the Subrcvr. A station I wanted to talk to
came on the 60 meter channel. I selected the TX to use VFO B. They
reported that I was well off frequency. I immediately signed and
investigated and found that when the Main rcvr/VFO A was set to a CW
mode, the transmitter set to use the B VFO for USB was not on frequency
during transmit only. During rcv it was on frequency.
What this means is that there is a "booby trap" if your modes between
the two vfo/rcvrs is different (even though you are not operating split)
that could cause you to transmit outside the band or in the case of 60
meters, well off frequency - which is very bad.
I wasn't trying to operate split with two different modes. I was
listening on two different bands with different modes.
