The email account is likely your backup email. I have a backup hotmail (live) account with the same name as my gmail. If I have issues with my gmail, I can use it for reset purposes. I doubt that it's asking you to enter some random email address.
Why would I enter a random email address?? I don't follow you.
Neither do I use g-x for anything, particularly on-line-storage.

Well, there goes that. For my google email account, I have purposefully setup another email, my hotmail account, as my backup email account. I can use it to change my password, and if someone else has changed my account, an email will be sent to both, for information. I also have my phone number as separate method for recovery.
Where my misunderstanding stemmed from: I didn't realize that Google would allow you to enter wrong information, and then email password reset information to some random email...
So, lesson learned: setup a means to reset your email that you won't forget. I can't imagine forgetting my email password, but if I did, I'd have multiple means to recover.
