It's such an absurd clause that if it was actually drafted by a lawyer, they were an absolute cowboy! However, bluff clauses are actually a thing and you will find them everywhere, but they will attract the attention of regulating authorities in a consumer contract. Still, they exist. My personal favorite is the frequently seen claim is the retailer reserving the right to change any terms of a given deal, which, for example, I recently saw on House of Fraser's website.
I also recently went skydiving and couldn't help but smirk when signing up to a clause stating that 'this skydiving school will accept no liability for personal injury, death or damage to property resulting from skydiving' - just... no.
