Technical name for receivers switching positions on snap?

[Staggerlee]

Ok so I'm watching some film and this team loves to line up in doubles or trips and at the snap the receivers will all start to run verts and usually the #1 and #2 receiver will criss-cross about 2 yards off the line. Similar to what the giants I think did to us at the goal line last year. This is done to mess with the CBs and safeties. What I'm wondering is if there is a technical term for it?

Rub, if the WR isn't careful it can be easily called a pick.
