JerryRigged, I think someone has swapped positions of 2 of your coil packs, and that is leading you to incorrectly assume the cylinder positions. The cylinders are as you state them to be on the passenger side (1-2-3 front to back) and 4-5-6 front to back on the driver's side. Since the coil packs are interchangeable, inadvertent swapping of 2 coil packs during a sparkplug change would be of no consequence.
