I'm quite sure he isn't. 100% is entirely sufficient for this purpose.
As far as the theme site cares, the devices are both 240x320 color screens, and that, is all that matters. In the event the Classic gets added to the theme site (more requirements need be met for this to happen yet), and someone uploads a theme for that device, ...then every other device capable of displaying it will display it in its listing also. The device specific sections aren't really device specific, so much as "meets a certain set of criteria" specific.
But, for your purposes I'm sure the part of this explanation that matters to you is "Yes, he is correct".
