Rules Analysis
Once possession has been established:
If the team that called the foul or violation gains or retains possession as a result of the pass, play continues without a stoppage. Players recognizing this may call "Play on" to indicate that this rule has been invoked.
If "play-on" is called before possession is established, and then the team that called the breach does not gain/retain possession, the "play on" call should be ignored and play should stop. The players involved must still determine if the breach actually affected the outcome, before determining whether the play should stand.
If the team that called the foul gains or retains possession, but the foul has impacted on their ability to continue play, they can call an indirect foul once possession has been established. This will stop play and enable them to make up any positional disadvantage caused by the foul.
