I can't speak for anybody else, but what I was thinking was, "gee, if I mount this sideways, it doesn't stick below the bottom of my fender, all the lines fit nicely, and it'll neatly drain into the catch pan without getting oil rolling down my arm, through my armpit, down the inside of my shirt, and into my tighty-whities", or something to that effect.
If you gentleman like giving that filter a quick twist, then having oil cascade across the entire outer surface, and drip randomly off some part of the bottom, then by all means, carry on. I'll be over here, not losing a drop, and not leaving a black rivulet from my hand to my nether-regions.
PS: with an Accu-Sump, I have oil pressure every time I start the car (and before I'm cranking the starter as well).
Your mileage may vary.
Do you have any pictures of your set up?
