I actually think his response is worded very poorly. Hes not saying ALL Legacy accounts = Standard Edition accounts. I believe he is trying to say that a Legacy Standard Edition account remains a Standard Edition account. Legacy does not upgrade your account from SE to CE.

If you have 1.0 CE you will still qualify for the in-game items, even if you are Legacy.

That's my interpretation of it.

The people that are getting screwed are the Standard Edition Legacy accounts. If they want both the physical and in-game CE items they have to not only get the physical CE copy, but also the digital upgrade. Pretty silly if you ask me.
