Structures for describing people, appearance or personality
in 好动, 好 is the verb, which means "like". So in your first example, it has 3 parts with different verbs, but all having the same meaning "like".

in your second example, if you follow with 头发短短的、黑色的, where 黑色的 is to describe hair, so it is not in parallel with other adjectives in this sentence. So the sentence is broken into 2 to avoid this confusion.
