It shows the coverage assignment of the user controlled defender, be it zone or man, and it draws a line from where the user defender is currently to where he’s supposed to be.

I’ve used it since release and find it very helpful. It appears to be the “defense pass coverage visual assist” setting. I tried turning it off and it didn’t show anymore post-snap, although it still showed pre-snap.

Here are some shots of zone and man, pre- and post-snap.
