I don’t know that I would call your standard method ‘standard’, at least not now.This name for it is probably only used in your particular area. Can you give some more details on the cir uit and then maybe we can work out what it is?
Is this wired in conduit or T&E, how many of what type of cables do you have at each switch.
There's only really two ways of wiring a two way, the standard method or the switch conversion, though there are many ways to physically connect them depending on each installation.
A standard 2 way has a live to the common of one switch, 2 straps between the switches and a switched live taken from the common of the other switch.
A switch conversion has a live to L1 and switched live from L2 at on eof the switches with 3 conductors linking the two switches (com to com, L1 to L1, L2 to L2)
yes but the metal faceplate is more critical than the back box. either earth the faceplate/s instead or link to back box with a fly lead.theres a link from the connector of the earth to the back box just cant see it in picture

It’s this method which causes borrowed neutrals when used on stair lighting.
If you take the feed to the downstairs light switch from the downstairs lighting circuit, then feed the upstairs light from the upstairs light switch, where do get the neutral for that upstairs light?How on earth does it cause borrowed neutrals? I've installed a lot of 2 way circuits this way and it's never caused a borrowed neutral to appear in my wiring?
The cause of borrowed neutrals is people wiring things incorrectly through lack of knowledge, care or just plain stupidity.

I had one the other day, the home owner was changing a bathroom light & thought it would be wired the same as one in another bathroom, apparently the light came on, then went bang when he pulled the switch. It was a bit of a head scratching challenge for me as there were 2 twin & earth cables ;-)I quite like jobs to fix lights where everything has been disconnected. The more wires the better, especially if some connections don't belong in the standard rose terminal blocks.
One of the best ones I had to fix was the switching for a light in another room that (for historical reasons) went via the rose in a different room. And a smoke alarm installer adding a wireless room alarm had mistaken the blue (old colours 3-core) for N. The light in the other room then never turned off completely.
this is what he had.
he had a 3 gang toggle switch. this is the wires he had at it 3 x 3 core into the first switch he had 1 x 2 core and 1 x 3 core into the second switch in the 3rd toggle he had 3 x 2 core doing 3 no of lights had a feed in and linked them all joint all neutral at switch dunno how he done go get him to draw it on a bit paper tomorow to let use all see
