I couldn't figure out why you put the step on the backside from the scarf. But, the sketch connected the dots so to speak. At least this is my take correct me if I'm wrong. When you start the weld with your hammer everything flows back into line instead of flattening out like a hammered thumb.

Yes, you are correct for a European scarf and is the reason why there is a sharp 45 degree angle on the front side of both the top and bottom leading edge..

The notch so to speak (where they both meet in the middle) becomes a sort of pivot point..

Really it's pretty cool and if done right you don't need to upset the material like you would with the convex American (though it was used in other countries) scarf..
