I don't see your point. Everyone knows your next class level is priced using your character level, or your ecl if you have a level adjustment. A normal level would push you up the chart to the next cost. A bloodline level doesn't increase character level the way a normal level does, so you don't move up the chart.
Or it moves you up the chart but doesn't increase your HD or have all the other effects normally listed under "what happens when you gain a level", therefore increasing your level but not in the way a normal level does.
"Not in the way a normal level does" means there are some differences from how a normal level works. The text then proceeds to list some differences. With those differences, "not in the way a normal level does" is fulfilled. You are assuming that there must be more differences than that and then deciding what those differences must be, when there is no reason to assume that.
You're assuming class levels grant benefits by increasing character level. This is not true. Class levels raise character level, and provide benefits. They do not provide benefits which increase character level. Character level is in the glossary, it is simply the sum of your class levels, and has nothing to do with what you get from those class levels.
Your position is that the author is saying we need a new mechanic to raise ecl gradually, we're going to use class levels instead of level adjust to get that job done. Fine, but if this is the case it is incorrect to say that they don't raise character level the way a normal class level does, because bloodline levels
would increase character level exactly as a normal class level does. They would give less benefits, which is irrelevant to character level, since it is just a class level counter.
The author used a negative, he wrote they do not. The clause "the way a normal class level does" would support your position, if and only if he detailed a method of increasing character level. He did not. Bloodline levels don't add level adjust, don't add hit dice, and specifically do not add to character level.
