Welcome to the 'ville!

Since you are not working into the tops of stitches, you are working around the bodies (posts) of the stitches in the row below, it will make a denser fabric, and you will not be progressing as far in height nearly as fast as you would be working into the top of the stitch as normal.  

You described your stitches 'on top of each other', which actually sounds like you are probably doing it right.  I don't think I've encountered post stitches in anything shorter than a DC (not that it isn't possible), but patterns with post stitches are real yarn eaters because stitches really ARE on top of each other, shorter stitches more so than taller ones.
