In return, he gets some influence. It is not clear what he is going to do with it.
Perhaps it is part of a devious though farfetched plan to sneak up on my lower right group?
He can't live on the lower side, but he may be able to make himself die slowly enough that he thinks that he can kill the surrounding stones. He can set up what looks like a ko.
It starts like this:

And I can't prevent him from playing L1, making a ko. ( If I take it myself, he plays M1 and lives )
However, to make this ko meaningful, he has to prevent me from connecting northward or eastward. Then he must win the ko about 4 times - once for each extra liberty that my group has.
It is a bit of a stretch, but it is all that I can see that makes sense for his two most recent moves.
