The champ after all, is always shown to be traveling around on all sorts of business, the E4 probably do something along the same lines.
If someone choose to say rooted to on city, like for example Skyla, since she has the airport to take care of, ask to be given a gym instead.
Gym leaders most likely serve a purpose in their community, like helping trainers in their area improve and the like. Who knows, maybe your character in game is simply lucky to live close to a PokeProf as to get starters from them, gym leader might do the same thing for other trainers.
As for OP's pic, they most likely have a pre-approved roster for trainers of different levels.
