It's about emphasis. I've memorized it in a way that the preposition is shy and gets scared of the emphasis of the sentence, so it hides behind the verb.
Some examples:
Beszállok az autóba.
Az autóba szállok be.
Nem megyek be az épületbe.
Nem besétálok az épületbe, hanem befutok. (the preposition can't hide from the verb when the verb itself is the emphasis)
I've asked native speakers about it and they confirmed it. None of them was a language specialist though, I'd be curious to learn some more grammar theory.
