First make sure the disc is at the central handler (2). Make note of what side is forced by the defense. Player (1) (the 'iso') pushes his defender (slowly) away into the 'open' side.
The central handler (2) can then throw the disc inside into the 'closed' side of the field, where there is now extra space. Meanwhile, player 1 stood still (which is why the play is called stationary isolation)
Player (1) is now able to run after the disc and catch it in the 'closed' side of the field, allowing for a break-throw to the next player in the stack (5).
As (5) catches the disc, players (6) and (7) can be the follow-up to finish the point.
An example of an 'end-zone cross' is shown here.
Player (6) may be able to catch it on the 'closed' side of the field, if player (5)'s marker is not yet on the right side (allowing another break-throw). If this is not the case, player (7) makes a good fake and scores the point on the 'open' side.
