The real danger is. if there is another incident similar to this one, in SQ or elsewhere, crew might decide not to evacuate based on this incident, and end up roasting all passengers. In this incident the crew judgement was correct or luck was on their side. In fire incidents on landing or take off, (Of which there are several every year), the recommended and safe action is always evacuate first. I am sure airlines will closely review this incident advise crew the correct action.
As has been pointed out in this thread, in real life (as compared to in the sim) no emergency incident is really similar to another one. I hope that a professional crew would assess the actual conditions in which they find themselves, and judge what to do without reference to any other incident that they might think is superficially similar, especially one that hasn't been analysed and about which the full facts are not known.
