I like to collect these too, I'm an old guy who likes real hard copies, I have about 70 of them from courses all around the country and the world. I know I have a few of the ones you show in this photo. I also have brand new books for Sand Valley and Mammoth Dunes, ready to be used in a month from now..
The NPCR is point for the ball which affords complete relief for STANCE and SWING from the condition from which you are taking relief, is no closer to the hole, and is nearest the original position of the ball (with a couple more restrictions). This sounds like we agree, take. This general description comes from the definition of Nearest Point of Complete Relief. As others have said, this NPCR might mean you have to drop in a bush or behind a tree or on the side of a steep slope on in really tall grass, you don't get a choice, you have to use the nearest. So make sure you know where your drop will be before you pick up your ball.
In your link, go to 16.1b, just after Reference Point, if you click on the phrase "nearest point of complete relief" you will automatically be linked with the Definition for that term. This is a really positive thing about the Rules of Golf online, in both the R&A and the USGA versions, all defined terms referenced in the Rules are shown as hyperlinks to the actual definition. You may want to read through the Interpretations on this Rule and Definition, they make it pretty clear.
What is there to be confused about? You haven't taken relief until you are taking FULL relief, meaning you aren't standing on the path (or whatever it is). So--- the closest position is the closest position. Otherwise, in the illustration below, relief would be at B2 if you were on the right hand side of the path (or whatever). Which wouldn't be relief.
