<p>I don't know if this is universal or not, but I personally make my schematics so that when looking at the pot symbol with the slider pointing up (as in VR1 above), the left, center, and right nodes should be the left, center, and right lugs of the pot looking at it from the top (knob side) with the lugs on the bottom (as they are oriented on the Drone Lab). Secondly, I believe you are correct, as it shouldn't matter as long as they have electrical continuity for all nodes as specified in the schematic. The actual orientation of wiring doesn't matter for basic functionality, but weird issues like ground loops causing interference can sometimes arise from creative wiring schemes. It's all sort of beyond my realm of expertise, but a basic wikipedia search for ground loop will inform you if you're interested.
