People who are experts at their domain are not always good at explaining things to others. This means that if a data scientist does not know how to code, they need to partner with a programmer and be able to explain things to them. Same goes for a bunch of other professions. For some people, it is easier to learn to code than it is to learn to communicate their ideas with people.
If you are not going to be able to implement something, whether in code, or with a saw and hammer, you must be able to explain things really well. If you can not do either, you will have limited ability to apply your craft.
