?I'm looking for a power supply for the 4018.? Is a 12 V DC 5 A supply acceptable?

I haven't yet purchased my DR5000 and 4018 but will soon.? I plan to use the Z21 app.? In preparation, I was watching videos on youtube and came across something that I thought was odd relative to setting up turnouts.? See, this video link, starting at the 3 minute mark.? ???I don't understand why one must add 4 to the turnout number?? Is that correct for the DR4018 + DR5000 + Z21 app?? Ryan has a nice video showing how to set up the 4018 with Atlas switch machines.? He did not mention adding 4 to the turnout number.? Can someone explain this to me, a novice relative to this technology?
