Right, and the text you quoted legitimately reads "Class levels of 'bloodline' do not increase a character's character level the way a normal class level does." It is blatantly explaining how there is a difference, and that they do not count towards "class level," which as you are arguing (rather abrasively) is the term used when describing ECL.

Further, if you really want to get into the specifics, ECL is defined as Effective Character Level, so trying to argue that it only refers to class levels is faulty in basis. For further reading, feel free to bounce over to the online glossary available here.
