The blocking foul is called due to illegal contact (block) as described as illegal activity in the principles of screening.

Not saying I agree with it, but 10-6-6 does say, "Contact caused by a defensive player who approaches from behind is pushing..."

I'd prefer it termed it "blocking", which explains why that's the signal I most frequently use cuz it makes sense.

Though this citation might not actually address the original post...
