[DeTomaso] fan belt sizing question

All,

Doing some pre-Monterey work and noticed for the first time the Water pump and A/C compressor belts have different top widths,
 one being 10mm and the other 12mm. The 12mm serves the A/C compressor.

Both are 36 degree angle belts, so I assume this means they both correctly mate with the pulley angles.

But why the different widths?

Does the wider belt, which also equates to taller, thus more fully contact the pulley sides, and increase grip abilities?

Or ........??

Larry - now I know why the A/C stopped working after San Diego ......
