[Question] Playing mutiple characters in a single SQENIX account

[Tobbit]

I've read a FAQ sort of answering this:

■Playing 3 characters simultaneously on the Windows version only
- One(1) SQUARE ENIX account
- Three(3) Windows version retail products
*Up to 8 registration codes may be registered to a single SQUARE ENIX account.

This lead me to question in which if I bought another retail of FFXIV and link it to my current Square Enix account that has my main account linked, would that mean I only have to pay for 1 subscription fee for two products?

edit: After doing more research, it seems I still have to pay a separate subscription fee for the second account.
