In my interpretation of those two claims you're comparing apples and oranges. The first claim is that your clothes will retain the scent for twelve weeks hanging in your closet. The second is claiming that your clothes will retain the scent through a full day of wear without reference to how long the scent lasts in your closet.

To me the biggest problem is the claim that this product imparts freshness. It doesn't. What it does do is impose a scent on your laundry. However much some folks might like perfuming their laundry it is the opposite of freshness which would be no smell at all.
