do I need more than one www.remarpro.com profile?

I apologize if this is the wrong place and if it’s a stupid question – I have searched but not found anything that answers my query:

I run 2 self-hosted sites on WP, the 2nd one I set up very recently. I have a www.remarpro.com profile for the first one, likeims.se, that I’m using here, for support. My question is, can I use the same .org profile for my other site (www.tamarillo.se), ie the same (support) profile for both self-hosted sites, or do I need to have separeate .org profiles for the different sites…?
