I believe he's responding to the characterization of the drive as a "Thunderbolt device". As the article and @vetinari note, the drive supports both Thunderbolt and USB. It's sort of a given that that performance would be different based on which "mode" it's in. One related complication of sharing a physical standard is that all Thunderbolt 4 cables work for USB 4, but the reverse isn't true. Ideally that would not be the case, but people want their cheap USB cables.
