That notice looks to me that the doh are just covering their arses and reiterating how they state formula should be made. Which is fine, I've never followed their guidelines anyway! With my other two I made the bottles in advance, stored them in the fridge and then warmed them up when needed.
Don't they make formula completely differently in the US? Without using boiled water? Maybe someone from the US can confirm.
