Hmm I think someone else has voiced a similar opinion on the wording here, and I actually do agree with you.

What was meant by this statement is really just taking care of plumbing and the visualization of how code relates to one another.

To give you a very basic/silly example of plumbing, if I add a parameter in a function used in 100s of places, doing the manual work to figure out what edits I need to make to those callers is pretty annoying and in most cases mechanical.

If you're lucky, you can do a grep + replace (or just use a default param), but in most cases I find it requires more manual intervention than that.
