It does not *require* higher revs. The engine management computer is, however, forcing higher revs in order to warm up the catalytic converter more quickly--which leads to lower emissions.

There's nothing strange about this at all. It's all taken care of in the engineering. The higher revs called for by the engine management computer are not the type of high revs that the manual warns you against.
