But, wouldn't that mean that if you share the same email account on your Desktop and Phone, that using a different key on your phone would mean you could not decrypt emails intended for your Desktop?

My understanding was that you can associate a key with your email address, does this just mean you would have two keys associated, one for "[e-mail] Desktop" and one for "[e-mail] Phone"?

You can encrypt messages to more than one key. You have to be pretty fussy to begin with to even have this concern.
