This isn't an extension of the one-year warranty. It's a clarification of the consumer complaint period and an acknowledgement of it. While EU mandates a minimum of 2 years, in some countries, this time period can be longer, like in Sweden where it's 3 years. However, there is a big difference between warranty and a consumer complaint case: Apple's warranty covers things that break after the customer has received the product - essentially a guarantee that the customer will be able to enjoy 12 months of fault-free goods - while a consumer complaint case covers defects and flaws (including false or erroneous marketing) that were present in the product before the customer received it. Examples of this can be a manufacturer claiming that an LCD screen is a 24-bit truecolor display while it is in fact an 18-bit dithering display, or claiming a certain resolution for a digital camera higher than the camera's sensor can actually provide.

If something in the product that was working ok and as advertised for 1 year suddenly breaks, you're not covered by Apple's warranty, and you're not covered by the consumer protection laws of the EU. If you within the established consumer complaint time period find that something about the product isn't as it should or isn't as advertised, you have a legal right to a full refund providing that you can prove that the problem in question accompanied the product when you received it.

The bottom line: you still just have 1 year of warranty, but now Apple also lets you know that you have another type of consumer right that extends beyond the warranty period.
