You are correct. Once the bleach is in the water tank and the tank is full, run it throug each and every line until you smell the clorine odor from each faucet. (hot & cold) Then let it stand for at least two hours, four is better. Once the time is up, drain it and flush with fresh water. If the smell remains, mix backing soda in the same mix as the bleach and run that through the system. Let it stand for 1 hour and then drain it and flush with clean water and you should be good to go.
