Optimal multiplier vs optimal mass myth?

[hs0003]

Apparently there is a rumor/myth going about that if 2 thruster rolls gives the same speed, but one roll has a better optimal mass than the other (again, same speed, boost speed, pitch and so on), the one with a better optimal mass will make a ship drift less than the one that achieved the same speed with a higher optimal multiplier.

Has anyone tested this at any point? Can anyone confirm/deny?

I can confirm that optimal mass vs optimal multiplier makes ship different flight model even if stated max speed stays same. But I can't really describe it and I don't think its as simple as "make ship drift more/less" - its very situational. Generally I just fly them and see what I like more.
