Doors – Barrel/“Paris” hinge pivot orientation

doorshinges

I've seen some doors in Europe with mixed barrel hinge (Fr. "paumelle de Paris") orientation. Unusually these have the pivot pointing up, but occasionally I've seen a door with one of hinges mounted the other way around, i.e. with the pivot pointing down. Is there a reason for this?

For outdoor use I understand this is a bad idea because a barrel hinge will gather water when mounted upside down. The ones I saw upside down were all inside doors. Also, it wasn't done because of the lack of proper parts (left vs right hinge). They simply rotated the hinge completely with the pivot installed on the door rather than the jamb. I don't get it why anyone would do this.

These hinges, when both are mounted with the pin facing up with pin side mounted to the door jamb OR when both are mounted with the pin facing down with the pin side secured to the door - it allows the door to be easily removed.

When one hinge is flipped the opposite direction with one pin pointing up and the other one pointing down it prevents the removal of the door. Pretty simple actually.
