is it your experience that the venting doesn't matter as much as just having more mass?
Some 1 pc also have similar designed directional internal vanes for drawing and dissipating air. Take DBA for example, both 5000 (2pc) and 4000 (1pc) series use the same “kangaroo paw” internal vanes.

I think for #91 specifically, he’s saying the marginal performance benefits don’t outweigh the cost saving from using cryo treated blanks. One can buy 1 pc with the internal vanes, then send to get cryo treated....or some sites actually sell cryo treated stoptechs.
