Well, currency entering the economy means inflation. And though there is no currency exchange, the unequal distribution means upwards pressure on the higher ranks in each level. That is, the ones who spent tokens regularly now have more peer-like competitors being created in players who have made Q increases they otherwise wouldn't have. The unlimited supply those players have is the upwards pressure that implies a player who was, eg, top 10% in their server-level is now pushed down and forced to increase their income/ token supply, to compete. If token buyers choose to continue buying and competing Nord benefits to the point of those players decreasing their total demand.
Unlimited token supply also means generating many more player at each level who are bumped way up in quality then sold in auction. This might not have too much impact because of the 99q auction limit at each level. For example, level 9 player at 145q doesn't really demand more tokens in his market, as a 85q player in level 11. However, anything that moves more players through the auctions means tokens.
I'd say yes, Nordeus could be benefiting, but I don't think they are allowing this for that reason. The economy could be complex, but they almost certainly have some "prime indicators" to monitor the "health" of the game economy.
