Answered: Using Y-cables with power expander?

Is it legal to use a Y-cable from the cortex into two ports on a power expander, then use another Y-cable from the power expander to two motor controllers? <R12> States that “You cannot ‘Y off a Y’ to have more than two (2) motors controlled by the same Motor Port”, but is the motor port counted as the Power Expander port or the Cortex port?

I assume the intent of the rule is to prevent a dangerous amount of current from being put through a single port on the cortex, however the power expander in this situation would prevent that.

Thank you!

No, this is not legal.
