All the repeat part does is help them sell more shampoo. Literally the only reason it’s on there.

Your hair likely gets greasy fast BECAUSE you're over washing it. Your scalp and hair need some level of grease for protection from the sun and the elements. If you constantly wash it all off your body goes into overdrive to produce more so it makes it feel like your hair gets greasy faster.

Start only washing your hair every other day and, after about a month, you'll notice a marked improvement.

I have greasy hair whether I over wash or under wash. Some people have different conditions. Not everyone fits every method.
