They are called "related" because they use the same notes.
So if you play random notes from the A major scale, they are indistinguishable from random notes from the f# minor scale.
So if you play f# minor pentatonic, you are by definition also playing A major pentatonic.
The only way a listener can tell which one you are playing is by context, emphasis, start and end point, etc.
So you can play A major pentatonic by slipping down 3 frets and playing f# minor pentatonic, accentuating the A notes and not the f# notes.
Of course you can also play these notes from the A fret. You don't necessarily need to slip down to the f# fret and play the minor pentatonic shape. But of course, if you are staying up on the A fret you can't just obstinately stick to the minor pentatonic shape, because then you will be playing a MINOR pentatonic! Obviously. For example, the second note will not be the 3rd fret above A, it will be the 2nd.
How's that?
