The convention of lining up the label and valve hole lets people still locate the approximate spot on the tire that corresponds to the hole in the tube after the tire, wheel, and tube have all been separated.
It is opposite here but my tire rim combinations run pretty tight, i.e. it can be a real pain to get my tires mounted. But I generally run performance tires which typically are tight to the rims. There is some variation between manufacturers and even between batches of tires, but in general I have to use irons to get my tires mounted where with different tires I could manually mount.
I agree inspection is easier off the rim, but I don't need to dismount the tire in total unless the tube or early tire inspection prove otherwise. Overall, leaving the tire half mounted is quicker for me.
