How to select the other vertices/edges after rip/rip fill If I select vertices or edges and use rip (same for rip fill) Blender creates copies of them and choses one set which is then selected and can be translated. How do I select the other set instead?

How to select the edge belonging to front face instead (without performing a translation and for more complicated meshes of course)?
Just place the mouse on the wanted side :
