If only those pictures were of the same thing. The first one is obviously the front of a rack, where all the cables are meant to be non-permanent to afford you flexibility.
The second picture is the back of a rack of punch-down blocks, which are meant to be permanent. The only time these changes is when there is a bad wire; vs the front of the rack, you change that wiring all the time. That being said, I've seen bad wiring, rather than be pulled out of the bundles, just cut and a new, supplementary cable put in in it's place, and not strictly part of the established bundles (but still neatly run).
The back of the racks are neat purely so you can be flexible on the front. Now, obviously, one can create neat front-rack cable layouts too, and potentially run into the problem you had redoing all the bundles, but the neatness is directly related to the intended permanence of the wiring.
