Place all cables in the clamp together........ I agree the standard is not clear, but the intent was always that all the I/O cables be placed in the clamp together.
The idea is to simulate transients being coupled between lines in cable trays, especially where noisey ac lines are run near or adjecent to I/O lines. It's not likely the signals would be coupled to one line and not to another; in fact, because of the very fast pulses, everything gets very well coupled very quickly.
