Can someone please let me know if this is true and what sites? Thank you very much.

I see you've got your answer just a flower for now.**

There is a separate membership for CuteEmbroideries and for AmazingEmbroideryDesigns. You only get all designs on the site you buy the membership for. The other sister sites, CuteAlphabets and AdorableApplique don't offer memberships, you have to buy the designs (or collect the freebies).
