How would that be wrong?
Different names refer to different aspects which relate more strongly to different qualities. Think of all of the aspects that a man is supposed to have. Be a helpful son, a protector and companion as a brother, a good loving husband, a protective and educating father, a good worker, an educated and intelligent man, have skills and abilities in using and repairing mechanical and electrical devices. Have skills and abilities to use all kinds of common tools. Have knowledge of farming or gardening, construction, hunting and fishing, knowledge of history, knowledge of science, knowledge of politics. Having the skills and knowledge to be able to provide for your family in all possible ways.
All of these things are different seperate aspects and different topics, and there are seperate words to refer specifically to each of these things. But a man is supposed to be advanced in all of these ways and more. If you are a father are you not also a son? If you are a husband are you not also a brother? If you are a scientist are you not also a mechanic? All of these things exist together and are not exclusive.
