Maybe Maryland hasn't given notice yet, and they are willing to delay their move to the B1G by a year in order to minimize damages in the lawsuit? If they haven't left, they get to see what the cost would be before deciding what to do. And they inflict costs and confusion upon the ACC, where any retaliatory countermeasures against Maryland (a conference member) expose them to expensive damages, and they don't know how to schedule. That motivates the ACC to settle.
This actually makes some sense from Maryland's point of view, if departing puts them at risk of a $50 mn exit fee plus as much as ~2 years or $45 mn of withheld league money (legally, they shouldn't be at risk of both, but since lawsuits are conducted in separate courts, an irrational outcome is not impossible; and even if they could eventually recover withheld money, it might take years and expensive court costs).
If this is indeed the situation, it could create quite a mess if the ACC doesn't settle.
If Maryland has indeed refrained from withdrawing (meaning the B1G has accepted a potential 1 year delay in Maryland's entry, having 13 members for one year), then likely outcomes are:
1) Maryland and the ACC settle for a small enough amount that Maryland willingly leaves for the B1G. Status quo. ACC is satisfied and B1G waits to see if it can create a B12 schism.
2) Maryland and the ACC make up, in which case either
(a) Louisville is uninvited from the ACC, and the B1G may invite UConn to replace Maryland;
(b) Louisville is uninvited, the B1G chooses to go with 13 teams and wait to see if they can arrange a B12 schism and choose their adds then;
(c) Louisville and UConn are invited together to the ACC.
