Loaded statement; sure. Technically wrong, nope.
As others have stated (and not just the above), he's technically correct. It's an advertising/political gimmick to play off of peoples ignorance.
That's where I find issues with the statement. It's similar to when the 8 & 16 bit console era were out, and games were 8 Megabit or 16 Megabit. I had tons of friends who were always trying to argue that their 8 Megabit game was better, even though my PC game was 6 Megabytes and had 256 colors instead of 15 colors.
