I think the implied conclusion may be a bit too far-reaching.

But it may well be a total waste of time to keep re-connecting the same dots over and over. I like to review my stuff, but when I do I prefer to focus on creative things like finding new avenues forward or realizing things that I had forgotten to even list, not on re-understanding things that I had already understood several times but had forgotten.
For example, if you have a little GTD project with tasks such as "Hammer nail into wall", "Climb ladder" and "Raise ladder" it will certainly speed up subsequent reviews if, when you first realize that there is a natural sequence between these tasks, you can arrange the tasks in the right order (or mark their sequential dependency in some other way). It helps you verify that nothing is missing.
Or when, for the first time, you realize that this particular little project can be regarded as a part of a larger project on your list, then it will speed up subsequent reviews if you can make a visible note of this fact somehow, such as by placing them hierarchically.
The initial connection of the dots certainly must be done by the brain. The subsequent repetitive re-connection of those same dots can be sped up significantly by having the adequate means available to support your memory.
As I said in an earlier post, a lot depends on whether you are aiming to manage only your short-term lists, or if you are also trying to keep your longer-term projects and goals in the same app. In the former case, you may not need much much "re-connection assistance" whereas in the latter case, when stuff is going to sit on your list for ages, you could save a lot of time by simply making the lists easier to re-read.
