DupEdge - output layer is not what expected at subD geometries

Hello, just a smal thing to know:

the feature output layer from the command dupedge gives a different result depending on the kind of geometry.

Steps to repeat the issue:
• create a surface and a dubd surface on layer 1
• switch layer 2 as active layer
• dupedge a edge at the subd and at the surface
• use the option output layer: input
→ the result are two curves from the surface correct on the input layer from the subd surface on the current layer.
If you use the other option (current layer) the result is inverse.
