In this case dropping one gear and going up a couple of hundred (which as pointed out is about all you could do at that speed) is not going to harm anything. The cut off isn't a drop dead line where one RPM over is going to blow an engine. There is a safety margin built in to deal with exactly this sort of situation.

Im sure you are aware that the true limit of the engine is significantly beyond the manufacturer redline, especially for over revving under nominal conditions like revving in neutral or missing a shift for half a second.
Sure, take the car to redline then accidentally money shift and you are probably screwed. But lets not compare apples to oranges. The OP went 400 over the suggested limit for a second.
