I can confirm That this procedure is spot on and it can done without much difficulty WITHOUT any soldering/unsoldering on Both Xbox one and Xbox One S wireless controllers.
I've just done button replacements on 3 ONE S Controllers and 1 Xbox One controller this week without unsoldering anything. All are working fine. The One S controllers have a bit more slack in teh soldered cables than the gen 1 controller so they were easier but basically you can twist the top board in place without straining any connections and have plenty of room to remove teh motherboard screws and do the button swap. The big trick here is controlling teh Rumble motors. I just used some Painters tape to hold them in their receptacles while i worked to keep them from falling out and straining the soldered connections.
Also regarding the time estimate the first one took me about 30 minutes by itself but once I had the process down it was a 15 minute process to tear down and reassemble.
