This way, all pulleys have to be cut with a gear pattern, they have more pulleys, and a longer & more expensive belt. I'm wondering what was in the way. ???
I'm not so sure the 3 pulleys need to be cut to match the cogs ...

so long as the pulleys have a bevel of some sort on the inside edge it will collect the belt and spin accordingly provided there is proper tension in the belt system ...

As for the pulley count and placement, I seem to remember a best practice of having a pulley between each cogged wheel in a machinist environment ... not sure if that applies to engine bays ... It's been years since I had that training ...
