Rope and Ride question

Continuing the discussion from Flight of the Lepus, Leaving Shootout Location (Sheriff Eli follow-up):

The shootout takes place at the location of the mark, and does not change for the duration
of the shootout (even if the mark subsequently leaves the shootout).

  • Section 6.1 Shootouts

Rope and Ride 3 :clubs:
Action • Cost 0

React: After a dude accepts your callout, but before posses are formed, boot your leader or their attached Horse to move your dude then the mark to an adjacent location that is not your home. Boot the mark.

My question is, would Rope and Ride cause your leader and the mark to leave the location of the shootout, thus causing them to leave the shootout? or, Is it that Rope and Ride changes the location of the mark before the shootout starts, thus the location of the shootout is where the mark is after Rope and Ride?

Short version: the shootout is at the new location.

Long version: Since posses haven’t formed yet, you are moving the leader and the mark to a new location. The shootout then starts at that location. Hope thats clear!
