Yes, your right there. Its the same relative major and minor prospect as in the major scale. Observe;

A minor pentatonic scale;

------------------------5----
--------------------5-7------
----------------5-7----------
------------5-7--------------
--------5-7------------------
----5-8----------------------

C major pentatonic scale;

--------------------5-8--
----------------5-7------
------------5-7----------
--------5-7--------------
----5-7------------------
--8----------------------

What I was saying is that if you were to compare a C major scale to a C minor, there would be differences, like the flatted notes. Plus you have to take certain notes away from each scale to make it a major or minor pentatonic, and thats what those scale formulas illustrate.
