Best move here?

Hello, this is my first post to the site so hopefully I do it right.

On move 131 of the attached game, Leela (0.11) says that D12 is the best choice and continues to suggest it for the next few moves. I don't see how that could possibly be a useful move. Can anybody give me some ideas on why Leela is suggesting it?

D12 forces white to choose one connection or the other - each has specific weaknesses that black can then exploit (later, knowing how white responded). In combination with for example a move like B13, this can become a very potent destruction of white - or at least black can get more forcing moves from the outside this way.
