Yes they do… it’s all there (bold is mine):
15. Calling Fouls, Infractions and Violations
15.1. A breach of the rules due to non-incidental contact between two or more opposing players is a foul.
15.2. A breach of the rules regarding a Marking or Travel breach is an infraction. Infractions do not stop play.
15.3. Every other breach of the rules is a violation.
16. Continuation after a Foul or Violation Call
16.1. Whenever a foul or violation call is made, play stops immediately and no turn over is possible.
10. The Check
10.1. Whenever play stops during a point for a time-out, foul, violation, contested turnover, contested goal, technical stoppage, injury stoppage, or discussion, play must restart as quickly as possible with a check. The check may only be delayed for the discussion of a call.
10.2. Except in the case of a time-out:
10.2.1. All players must return to the positions they held when the event that caused the stoppage occurred, unless specified otherwise.
10.2.2. If the event that caused the stoppage occurred after the thrower released the disc, and the disc is returned to the thrower to restart play, all players must return to the positions they held when the thrower released the disc, unless specified otherwise.
10.2.3. All players must remain stationary in that position until the disc is checked in.
Your scenario 2 only happens in the case of a time-out (as stated in the rules).
