Comparing specs between Linux and Android is an Apples vs oranges comparison IMO. I think a lot of people are unaware of the huge overhead that Android (and even iOS) has.
The intention of the statement was to show that it is low-end hardware at a high-end price point. Performance of eMMC flash memory isn't magically going to be "hugely" faster because it's ran on a different OS. That 720p screen will perform the same too.
Android performance overhead is not relevant to this.
