Yes it can work like that.
The branch could ask its members, regardless of points, who wants to go to Burton, ten reply that they do so the branch requests 10 tickets from the Supporters Club.
The branch secretary is told they’ve only got five, not the ten they wanted. Then the other five are sourced through different paths. If they have five members with enough points they can get them from City’s ticket site like everyone else even though the five with the high points might not want to go.
So five members get their points added to their total, even though they may not be going to the game, and five get their points added as they bought them through the branch, and may have had less points than needed before it sold out.
