Why in that order? Because I used to keep my keys in me left pocket and wallet in my right (before the smartphone was a thing yeah I’m old), but once I got a smartphone I didn’t want to damage the screen, so into the right pocket the keys went, and only the phone goes in the left pocket and nothing else so it won’t get scratched.
Right pocket, right pocket, left pocket.
