The analogy is not perfect, Rich, but the essence remains the same.
The connection is established and it is this establishment that explains the result.
There is a first. However, in your reply, it is not recognized. That means you skipped a step, put it under the carpet.
The hollow pipe is established, that is the first step, then the action on one side is found to be connected to the action on the other side.
The beauty or surprise is that the hollow pipe can get established at all, and it tells us how important connectivity is. In essence, the option of connection is already there (hence, your not mentioning it as a first because it is already assumed).
The difference between quantum mechanics and ordinary physics is that quantum mechanics has that automatic connection; it is inherent.

I am reminded of rolling the die.
When I roll a die, I cannot know beforehand what the resulting outcome will be.
Yet when I roll a die one million times, I can predict pretty darn well what the outcome is going to be.
That means we have two outcomes in which one outcome cannot be known with certainty beforehand and the other can be known with certainty. That may appear a conflict, but it isn't.
Furthermore, when the die shows me a 2 on top, then I do not need to lift up the die to know that 5 is on the bottom. So, when standing with uncertainty (rolling the die once) there is certainty nevertheless about the number not showing, found on the bottom.
