Is this diagram wrong?

I can't see an issue. Maybe it's showing a commercial lighting system.

Imagine there is a SL feed passing by an area in a shop where you want some lights.

So you redirect this feed to the Wago JB and take all the feeds out to each individual fitting.

Save using individual JB's and gives one cable at each fitting, easier to work with.

Use them regularly now
Replacing flourescent fittings mounted on besa boxes and the cables fail to reach the new term block, terminate the old wires into wagos usually 2 or 3 port, extend in singles to the term block.
Also within 2d fittings for similar thing or where theres a loop feed to link out

Thing i found though dont strip them too short you need to see the copper the other side of the clamp when pushed home.
Though do agree they dont feel as firm as you would expect

As the Bishop said to the actress!

I bought a load before I packed up S/E in 2005. They are great, but, joking aside, I do agree.
