Unless a greater emergency occurred which prevented them either landing safely overweight or discontinuing the approach then this should not have happened. If you can accelerate to V1 and stop on a runway then you can land overweight on it. Ideally if you have time you go and dump fuel over the sea or above 10000ft, which also gives you time to plan a single engine approach. If you must land immediately then you can safely do so having actioned the overweight landing checklist which determines flap setting to ensure adequate go-around performance. If you land overweight then it requires an overweight maintenance check but as the aircraft had a faulty engine then not going to cause any delays to getting it back in service!
Spending more time problem solving rather than rushing into an approach would have prevented this (unless getting on the ground immediately was imperative).
The min height to jettison fuel to ensure it evaporates before hitting the ground is 7000ft in winter and 4000ft in summer.
