I disagree, "copying" it up higher is the same as playing the pattern in a different postion..... the focus should be on teaching the "pattern" not where on the octave it's played.... and many people use it on the bottom octave too so I think I will just say that I don't think this should be done... imho!
Teaching E minor pentatonic in the open position is great, but since the whole point of this diagram seems to be to simplify things to the millionth degree, I personally believe that a shape such as the minor pentatonic should be displayed in a fretted position, if a guitarist is using this diagram to learn their scales, then it's unlikely they'll have the knowledge to (confidently) transpose a scale position utilising open strings, to a position on the fretboard using fretted notes.
I'm not denying the fact that there are many licks/riffs which utilise E minor pentatonic in it's open position, it's just there's technically 11 more keys in which you could use the fretted position, which is why I think it should be included, imo!

I've never been able to work out scales from those diagrams. a little help needed :s
These diagrams help to teach scales are shapes, rather than actual notes, or intervals, or scale degrees etc. They're particularly useful for seeing how different positions for the same scale can link together across the fretboard, ultimately increasing a player's knowledge of how to play in key in more than one position.
Can you see how each individual shape refers to a section of the guitar neck? I personally use these shapes in combination with the scale degrees and/or scale formulas from their relevant keys, as on they're own their useful, but you can miss out on a lot of important stuff without reverting back to the actual notes being used.
