The composition if the watt may be different though.
300w at 90rpm requires an #average# torque of 31.83N.m
But that same 300w at 90rpm could also be achieved by 63.66N.m for half of a rpm and 0N.m for the other half for example or any other ratio which averaged out to 31.83N.m over a revolution.
I would say that most people are forced to pedal differently. It's the same difference between peddling up a smooth flat road vs up a steep hill or through sand/mud - you can be doing the same watts and rpm but the pedal stroke and muscle demands are different.
