Likely they eventually realized that “winnings generated” could mean only points already scored (since that’s what the wording implies).
Also, I wonder what originally inspired the ’rule juggling’ that enlarged the 3-foul penalty? Maybe they thought straight pool was losing popularity because long, intentional-foul safety battles were boring spectators, and the BCA thus wanted to encourage more aggressive play (?)
BTW: Not-so-good players might choose the BIH option, even if “OBs in position” were still a solid pack. That would preclude your opponent from taking the initiative by accomplishing a successful ‘opening break’, and leaving you the choice between an intentional foul or likely disturbing/opening the rack with a long safety attempt (you could easily freeze the CB to a corner ball, and only brush it while lagging to the headrail).
If your opponent is good enough to runout, giving up the larger score penalties would still likely be preferable to leaving him any opening. But, taking 3 fouls yourself would just turn the tables, which might make for a very long game (both players with deep neg. scores). Likely why the option rule went away (?). Forcing the ‘re-break’ probably presents the best likelihood that a player will eventually get open.
