(I don’t even speak English every day anymore, so I could be wrong).
You’re not wrong. I think some of it is the difference between casual speech and formal writing (people are more likely to say “after being” but write “after having been”, especially in published work)**, but some of it is also just poorly phrased. It makes enough sense to a native speaker to get what the problem is asking, though.

They said goodbye at a given position and are then leaving each in a different direction. They are starting to move at the same time from the same point.

Wait, we know their position exactly? That means we have no idea what their velocities are!
What? Velocity too? Now we know nothing!!

Is he due north of the starting point, or of the girl? If the former, he is traveling due north. If the latter, his 5ft/sec velocity has a 1ft/sec eastward component, and we need to calculate the northern component.
