You forgot to list step 4 which is to put the lense in the disinfecting solution. We're talking about rinsing the lens with tap water before placing into the eye.

They also specifically state NOT to use tap water:

"Never rinse your lenses in water from the tap.

Tap water contains many impurities that can contaminate or damage your lenses and may lead to eye infection or injury."
