All you need to know to recreate this glitch is in the picture, nothing behind the blocks. The powered redstone is facing the block with the torch on top of it, but the block is not powered as shown as the torch being on. I noticed that if the block with the torch on top of it was adjacent to the direction the torch powering the dust, then the block would be powered. So you should either make it more clear that the dust is facing only two specific directions, or make the dust power all blocks next to it, whichever one was intended.
