This is actually required by the same EU-law, Directive 1999/44/EC Article 6. They need to do this for all EU countries, in the local language.

Not sure what the UK law covers under this "consumer law". But that coverage-gap is huge, so I imagine it's particularly in the interest of Apple to define the route of action for the consumer, as they only provide 1 year of warranty as a manufacturer but the SELLER (!) has to provide 6 years of protection.

Side-note: I see the page repeatedly refers to footnote "2" for the seller, which I cannot find on the page. Would be interesting to know what they meant to say here...

I mistated in my original comment, this page is not to do with UK or EU consumer law, they are explaining your rights established by UK contract law which are hundreds of years old. Any purchase of anything from a haircut to an airport building is covered by this basic law because whenever you buy anything in the UK a contract is created, regardless of wether you signed anything or not and this contract gives you certain rights in law one of which is that the thing or service you paid for should do what was advertised.

Most retailers don't go to the trouble to explain to their customers that they are also liable for the faulty design or manufacture of the products they are selling for up to six years under simple contract law on their websites, at most they typically say something like 'this product is covered by a warranty and this warranty does not affect your statutory rights', you would then need to go away and research what these rights actually are.
