Match Play and Stroke Play Comps in same round

The R&A state:

"If a Committee chooses to allow players to play a match while competing in a stroke-play competition, it is recommended that the players be advised that the Rules for stroke play apply throughout. For example, no concessions are allowed and if one player plays out of turn, the other does not have the option of recalling the stroke"

So, both players will first have to be in agreement that they are combining both forms of play. If so, then they are effectively playing Stroke Play rules whilst recording hole wins/losses after holing out.
