I wouldn't assume he's right. There's a reason DUI defense attorneys tell you not to take the breathalyzer test.
Anyhow, refusing to take the test isn't a crime. However, since the privilege of having a valid driver's license requires that you consent to such tests, your license will be administratively suspended (i.e. no need for any court proceedings) for the refusal. But that's not even close to the same thing as a crime.
The thought of implied consent being a "crime" is not necessarily correct, so that may have been poor wording, but you're right that the penalty is increased and that in many cases you lose your license immediately.
As far as who is "right" or not, all I can say is that there are other things that often get you convicted, so I would not necessarily follow the ambulance chaser DUI attorneys, but you are free to do whatever you choose, just let me know how that turns out for you. They are the following:
--a sworn officer's testimony
--the video of your road infraction (aka "swerving" etc)
--the fact that there was an odor of alcohol
--the video of the field sobriety test for the judge/jury to witness + again...the sworn officer's testimony of what they saw in this test
--the fact that you refused to submit to a test, which is automatically a DUI charge in all 50 states (most people who aren't drunk don't refuse the test)
In other words, many DUI attorneys' hands are tied after they see the video evidence. They no longer can receive a plea deal in many cases due to the damning evidence that is presented. On the other hand, if you blow a .09 or a .10 or something that isn't considered "too bad" there are a lot of times when your attorney can plea down to a reckless driving charge instead based on other forms of punishment such a fines/classes etc.
You won't get that opportunity too many times if you refuse to blow or submit to blood. If anyone could get off of a DUI by refusing to give a test then why wouldn't everyone do it? The answer is because they don't need that as proof nearly as often as you may think.
