The thing is, most romantic relationships fail. If it’s someone you met online or even a friend of a friend, you likely won’t see them that often after you break up, which is decidedly not the case for a colleague. So while it might work out with a colleague, and the odds aren’t even that bad, more caution is warranted.

Of course, it’s probably not terrible advice to tell everyone in a breakup to treat their soon-to-be ex as if they will one day be your manager. It’s just not likely that everyone will be able to follow through.
