Yes.
Most contest software that I am aware of will not allow
simultaneous transmission on more than one radio. The
computer can only key one radio at a time. Some ops use
two computers for SO2R. In such cases, they must build
a lockout device to prevent simultaneous transmission.
Receive audio switching is left up to the imagination,
but only one transmitted signal is permitted for Single Op.
