I did a little research, and while strange, it sounds like that was done in some cases for either EGR, or to improve shutdown smoothness, and possibly for engine braking (like an exhaust brake on the intake). It's not common, but Toyota, Nissan, VW and Mercedes have all done it at some point, mostly on old designs.
