This wording leads me to believe that you can not connect 2 spikes to a solenoid but you could connect 2 solenoids to a spike.

I believe their intent was to say:
Each speed controller and relay module must be connected to one, and only one motor, actuator, or compressor .

It makes a big difference.

Actually, it makes perfect sense the way it is. This way, motors/compressors cannot be connected straight to power sources - they must be connected to a speed controller or relay. And you cannot double up the speed controllers/relays to create parallel circuits to power the motor in an attempt to double the available amperage.

If it was the other way around, as suggested, then every speed controller would have to be connected to a motor. But motors would not have to be connected to speed controllers - which could lead to big problems.
