Does anybody understand the "next chelsea manager" rules

The rules according to BCM2


Who will be appointed as the next first team manager of Chelsea FC?

1. Subject to paragraph 2, an appointment described by Chelsea FC as ‘interim’, ‘caretaker’, ‘temporary’ (including an appointment described as ‘to the end of the season’) or similar,  will not constitute first team manager.

2. Notwithstanding paragraph 1, an individual appointed by Chelsea FC on an ‘interim’, ‘caretaker’, ‘temporary’ (including an appointment described as ‘to the end of the season’) or similar basis who remains manager in that capacity for at least 10 completed consecutive English League games (including over the course of more than a single season), will be considered to have been appointed as the next first team manager for the purpose of this market and Betfair will settle the market accordingly on that person.

3. The actual duration of the manager’s contract will not be relevant for the purpose of this market.   


so basically if chelsea appoint a manager on an "interim (or temporary) basis until the end of the season that will not count as their new manager. 
however if their interim manager remains in charge for 10 league games or even to the end of the season, then he will be regarded as the new manager.   

does this mean that a temporary manager is NOT the manager until he has completed 10 league games, and then he IS the manager (even though still temporary or interim) .
