It seems the "notes" pages are a standard in the industry... I'm just curious why that is.

Those "notes" pages are simply the result of the printing process.

You see there are certain standard sizes for professional printing. So depending on the size of the sheet that is used and the total number of pages of the endproduct, that leads to unused space = otherwise empty pages.
Based on the above figures you will usually see the total numer of pages being a multiple of 8 or 16 (including the "notes" pages; while a "page" for that matter is the front and the back)

In other words, those "notes" pages simply exist, because it is cheaper to have the whole product printed on as few sheets possible instead of having just one set of pages per sheet. (It's a matter of storing the printed / cut segments before final assembly that is too expensive for "low volume"-products like booklets)
