Exactly. It's likely been there for years and years, and the owners of that apartment/building never took adequate care for it. My aunt and uncle's home has a balcony that goes off their master bedroom, but no one ever goes out on it because they've never taken the time to keep it properly maintained and don't think that it's safe anymore.
If the metal was rusted or loose at all, having four people climb up on it and leap up, forcing pressure down on it could easily have loosened it to the point of making it fall.
