My 2010 Audi A4 does this as well. If you think about it, your wipers spend most of the time in the Off position (unless you live in Seattle). The rubber will eventually get misshapen on the side which is constantly pressed against the window. This helps prevent that from happening.

It's a German thing, and it's a good thing.
