Nah, its just a gc summary. When I was playing zs and switched to iw and I didnt activate green-coins account (btw, I had a really small ammount of gc in IW), I had different greencoins in iw (btw, it was like ~5000 gc). But when I did activate my gc account, I got more gc then I was having before, in zs. But after happened something weird, I lost my gc and then all the gc that were in zs were "copied" to iw, so I had the RIGHT ammount like I had in zs after disconnect. Almost the same happened in tf2, but my gc didnt disappear.
