Is the last sentence about the first sentence?

Do the bold parts make the OP facts ("clips the BR's heal as she's running"), clearly INT? Does that conflict with "maybe not so much if the ball contacts the unknowing BR"?

What he said is that if the BR interfered with the ball on a U3K, it is a dead ball, the BR is out and all runners return to the base last touched at the time of the INT. IOW, there is no requirement of intent on the BR's part. If the umpire judges INT, it is INT and rules should be applied at such.
