I'm assuming you are referring to this tutorial.
You are right! That is one way modes can be used. The point I'm trying to make in that pentatonic theory tutorial is that the pentatonic "boxes" or "frameworks" can used as a visual guide to play many different modes. However, that's a relatively specialized & advanced concept & not essential to learning & playing the basic pentatonic scale.
In general, there are 2 ways of looking at modes & you have to specify which one you mean.
1. Structural: each mode relates to a parent scale. So you are always in one major scale, G major for example, and the various modes are just ways of playing a G major scale, but starting on each note in turn. Often this is used to stay in one key, but play over the chord changes within the key.
2. Ornamental: You just play whichever mode you like the sound of at the time regardless of the key. This requires that you know & apply the scale or mode interval formula.
I have 2 tutorials on modes that cover both of these approaches in detail.
Hope this helps! Please ask more if necessary. Have fun with modes!
