  <p>I have gotten to step 264 and it seems odd to me that the single back bricks have a hole in them as they seem to go in sideways in the picture blocking the holes - hence only a single solid brick was really needed?</p>

  This is likely correct. Here's the instruction step that you mentioned:
  
  [![Step 264](https://i.sstatic.net/PjEMB.png)](https://i.sstatic.net/PjEMB.png)
  
  In order to keep costs lower, TLG tries to limit the number of unique elements in a set and in an individual bag within a set.
  
  The part you mentioned could have been a 1x1 system brick, but using a Technic brick here also works fine. Bag 9, the bag used for this step, already includes 1x1 Technic bricks as they are needed for subsequent steps, such as 265:
  
  [![Step 265](https://i.sstatic.net/kTuYR.png)](https://i.sstatic.net/kTuYR.png)
  
  None of the other steps related to bag 9 use a 1x1 System brick. It is likely that the 1x1 Technic brick was used in step 264 in order to avoid having to include another element in this bag.
