"Sweeps it's orbit clear" is actualy a mistaken rephrasing of the requirement.
The requirment is "has cleared the neighbourhood around its orbit."
And further to this, 'cleared the neighbourhood', has a more specific meaning in IAU terminology. It refers to objects that share the *same* orbit as each other, not cross each others orbit.
