hmm i remember that i got such a question when i tried to log in my xbox account on my pc some months ago. they send me a code to my e-mail address which i already use since 2005 for my xbox account and i had to use this to get access to the account on my pc. so no clue why you have to have a new e-mail now and can't use your old one.
steam has something similar with the steam guard. if you want to log in with a device you never logged in before they will send you a code to your e-mail account or something like that.
and if you use this code they ask you if this device shouldn't get this security procedure in the future or if you want this also the next times.
well, something like that, that's probably not 100% how it works.
