I interpret that as:
There are no limits on how many lead team members can be on the lead team at any given time.
(so therefore its not a valid reason for anyone to be denied)
That was all. Feel free to tell me how much my interpretation is wrong. Have a good day

That part of the policy is more applying to the fact that the lead team cannot use a reason such as “The lead team is full. We cannot accept anyone”. However, LT members can still state that they believe they do not need anymore LT members due to work on the server for example, they may not see any reports being left for ages and see other staff being dealt with by the LT quickly. If they see this happening then they may decide to get more but overall they would look for what Nick is doing in game/forums.
