Over-reving isn't really the end of the world. If you maintained your revs in the red under heavy load then that would be bad, especially in situations when there is a poor tune, excessive heat, extra stress/hp or other factors that could occur outside of a stock motor.
Even a brief over rev can be disastrous. But that is if you drop a couple of gears and shoot it up a 1,000 or more RPM. This is when you bend and break things that are just not designed for that sudden or intense of an impact. It is the abruptness of the increase that causes issues not the duration.
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.
