That's basically it. So say you had 10 people on your team, each person gets 9 votes. Say someone wanted to give only one person all their votes, the recipient would accrue 3 votes (sqrt(9)=3). Or they could give 2 people 4 votes each which would accrue as 2 votes (sqrt(4)=2) each for those two people and then you'd have one left for someone else. Then you tally up all the accrued votes (not votes spent) for all the people and then you'd be able to rank people according to how helpful they are (but this ranking wouldn't be transferable outside your team; you can't use it to compare them with the helpfulness of people on other teams).
