CL on 34gal Cube

It's not unique to the Reeflo pumps which have the motor shaft fixed to the impeller.

I have a Iwaki MD70RLT (mag drive) as a return with a union/valve on the output. Full open 2.24amps, with the valve closed 1.45amps.

As for Reeflo statement, on the surface could be contradicting if trying to link the whole article, but taken separately okay if just trying to simplify the principle of reduced flow and head-loss against pipe size. I'll still be using their product.
