He means putting the brick top and bottom textures on the sides, that's possible.
I don't work with brick coding much, but in a lot of bricks, you'll see a text version of the brick. It has "u" for up/top and "d" for down/bottom. I assume with some coding, this could be adapted to put the u's on the left, and d's on the right (adapted since it'd also need the other...code) And it should texture correctly.
