Syracuse v Virginia RA play - Higgins

[CallMeMrRef]

Does any one have a clip of this play. Higgins is one of the best, but it looked like the defender in the play I am referring to was at least a foot in front of the ARC. Believe 1st half. He pointed to the arc and I believe the commentators mentioned it as well.
Question - if defender establishes initial legal guarding position in front of the arc and steps back with one or both feet to brace for the contact (legal movement) does it matter where his feet end up? Not saying that is what happened on this play, but thinking that situation might be confusing.
