The sequence of loading chargers is down, up, down, up, down with the base of the cartridge at each end of the charger flat against the inside of the charger. This was drilled into the head of several million users of the Lee Enfield or SMLE, and it works. If it did not work, you would be speaking German right now.
You are thinking too much. Quit scratching your head and try it.
If you load the Lee Enfield MAGAZINE with the rim of one cartridge behind the rim of the lower one, then it will jam.
The Lee Enfield uses a double row magazine. When the cartridges are loaded properly into the charger, and put into the magazine correctly, then they will not "rimlock." One of the problems is that people do not give a good push to the cartridges when loading with chargers. If you bobble it or go slow, then a potential jam might occur, or the cartridges spill out of the magazine.

Well, the next EOHC Milsurp shoot is coming up in a couple of weeks. I'll try using both and see what happens.
