You can change the expiry date of your own key, but for other people to be able to see it and avoid having your key show up as expired, you must publish the new (key? signature? not sure...) and others must fetch it before the expiry date hits. I think what happened is that you edited the expiration date of your key and published it, but the other person didn't get the updated version before their copy of your key expired.
