I'm not so sure that's the case, when combined with an extended service contract. The "original warranty" was only one year, and this language seems to say that the length of the extended warranty offered by Amex after the service contract is equal to the length of the original warranty, not the length of the service contract. Although I admit, the language is ambiguous and you might luck out with the right Amex agent (when attempting to make a claim in months 36-48)
