If wires supports are stressed individually inside the similar duct, then those stressed strand will allow against those unstressed ones and trap them.

If wires/strands are stressed individually inside the same duct, then those stressed strand/wires will bear against those unstressed ones and trap them.

Therefore, the friction of the trapped wires is high and is undesirable.
