This should really be the linked article, much more informative. The charts at the bottom are particularly helpful for understanding the sequence of events (and seeing the conflict between standard departure and go around routes).

It will be interesting to see the investigation for this, as a layman I don't know if such conflicting routes are standard, and how ATC is supposed to respond to such a situation (presumably not by leaving it to the pilot to avoid, like in this case, however).
