Can one PWM control 2 Victors for Tandem Motors

I am a mentor for 2 teams. Two CIM motors per wheel appears to be disallowed with one Victor, see below. Can you use two Victors (one per motor) with a common PWM input to get around? The motors would have tied output shafts via the transmission. Is the Inspection Item 300 Rev E the final word?

----
RULES: REV E, FEB 5, Inspector List ITEM 300

"Motors can only be driven by one Victor or Spike with only one motor per permitted per Victor/Spike"

This complies with rule R-62 I think,

but the old inspection Rev D, JaN 25, did ALLOW IT:

Motors can only be driven by one Victor (although a Victor can drive more than 1 motor).

Thanks!
