So therefore, the 45 day review needed to be within the 90 day timeframe. Failing to perform the review within the 90 days does not negate the requirement to perform it. You are putting the cart in front of the horse here (surprise).
You're completely lost in your own spin. Try again. A 30-day review is mandated; an extended 45-day review (aka investigation) is not mandated unless two specific criteria are met.
