That's pretty amazing - I've seen threads (may have even started one for myself) and the only primary CDW coverage I've seen was some of the Chase cards and Diners.

Now, having said that - there is some very strange wording in there:

"In the United States, the coverage provided by this benefit is primary. Outside the United States, the coverage provided by this benefit is primary even if you have another insurance policy".

Given what the first sentence says, the second sentence is pure surplusage and adds nothing. In fact, the second sentence makes a lot more sense (as in it would have function and purpose) if the word "primary" in the first sentence were replaced with "secondary." Makes you wonder if there is a typo in the first sentence.
