Yes, as others have said, the Amazing Fit patterns have instructions that are for fitting as you go. It depends whether you want to do that or not. As long as you are not brand new to sewing, it's fairly obvious how to leave out the fitting bit if you want to, but I do see how it could be confusing for those who like to follow the instructions line-by-line as it is not immediately clear why you are doing strange things like tacking the side seams wrong sides together.
