Preview is can be skipped for a postview. Getting into the photoreading state takes a matter of seconds once you've done the steps often enough. Deep breath in state the purpose and you photoread.
Nothing was skipped just like when you first learnt to read you took a while to guess the words and now you just zip over them with recognition. Same as hopping on the bike... you used to have to check how you planted your feet before you kicked off to start moving... now you just get on and go.
