I't looks as if I mount it the other way around, oil will just run right through without even touching the axle?

You need to rotate it (some call it "clocking") so the oil inlet is at the top and drain vertically below it.
Turbos use labyrinth seals to keep the oil in, they will leak oil into the inlet and exhaust (making lots of blue smoke) if the oil can't drain out easily.
The oil in the top port will be spread along the shaft and to the journal bearings, from there the whole centre section is open to drain out the hole in the bottom.
