Following the same path multiple times between two points might be boring and mundane. Still, consistency can bring a certain amount of comfort. Repetition is close to consistency, and repetition and consistency can often lead to great things. Practice makes perfect, or so the old saying goes.
The path between two points may not always be the most efficient or even practical, but that should also be measured against the results and what is wanted when you are trying to get from A to B. Just traversing the distance is one matter, but if you are retracing your steps and looking for ways to improve then that consistent behavior also gives you a benchmark to measure potential improvements.
When trying to maintain a consistent approach leading to perpetual improvement, continuous review of that path is necessary to ensure that improvement opportunities are taken advantage of. As muscle memory provides for consistent behavior, it does no harm to look for and find better exercises to work through.
Consistent interface elements, due to their familiarity, enhance user experience. Users can learn the meaning of an element in one area and expect the same behavior when they encounter a similar element elsewhere. This consistency breeds comfort.
Consistency begets simplicity by its uniform nature. Complex systems built with consistent design can have their steep learning curve smoothed out with consistent design and behavior. Stay the course, and be consistent.
