Probably because I didn’t know any better! 
In the absence of a drag chain system, I found that the cables could get in the way of the core upper bearing bolts. I actually had one cut on the earlier Little Red build fail when the router power cord got in the way of the core, causing the X (my Y) axis to skip steps. I wanted to have everything well out of the way for this build, and I remember seeing a “pogo pole” method that seemed interesting.
