Delay + Poor Gate Choice = Insult + Injury?

Coming back from O'Hara last night we were delayed an hour due to weather. There were a lot of people on board with connections, and some with int'l connections; as we were deplaning in concourse T there was a page: "The four people who are connecting to a Lagos flight - your plane is waiting in Concourse E."

My question: Why did Delta bring us into gate T-2 (the end of the concourse) when many Delta gates much closer to the terminal were empty? Bringing us in to the end of the concourse added insult to injury, so to speak, and either Delta held the Lagos plane longer than they needed to otherwise or those 4 people missed their plane.
