Concrete header below a second story door.

I don't get a lot of CMU houses here, let alone a two-story one, but this one I noticed the second floor exterior doors have a header underneath them.  Is this typical for a CMU build?  BTW, there is a header above the door as there should be.

 

I checked and this is does not have a sill.  Like I said, the CMU's I've done prior were single story, so if this is a common thing.  Great, I learned something today.  But the brain in me, says a header under the door, doesn't make sense.
