They’re not hurricanes and not even be ar hurricane strength when they make landfall. It is somewhat doubtful Laura will even survive interaction with land before making the Gulf. And the two storms are different timings of making it through the Gulf...so, no, this is just more Weather Channel (which I used to really enjoy watching until they went all in on climate change) hype.
I saw one meteorologist speaking about this today; he suggested that often, in a situation like this (if those predictions remain) one storm may suppress the other.
