Suppose a guy doing pushups to failure slowly, then his red fibers will do work, what will happen when he is about to fall and cannot go further?

Correct. Try this experiment.

Go into a gym and get to the cable cross over machines. Do cable cross overs at a weight that you can do around 40 reps to failure, and do them real extra slow at about 3 seconds up and 3 seconds down. Guessing the exact amount of weight for this may be hard, but try. Now as you start to approach failure, suddenly, increase your speed so that you're doing an all-out effort. Notice how quick and easy the weights are coming up now that you're lifting fast. The red fibers have been hit to exhaustion, but the white fibers have been spared.


How cable-cross is done.
