You don't want to keep your private key in cleartext on your email provider servers, do you ?

It means if someone you want to impersonate uses the Web Of Trust, i.e. their key is signed by other people whose keys have been signed the same way, you can generate a GPG key for which all of these signatures are still valid.

For example, if an attacker gains access to a victim email account, they could send to their contacts a "trusted" key (as explained above) and then use it to send signed documents to the victim's contacts.

This would defeat an adversary "paranoid" enough to check a key signature, but not paranoid enough to obtain a clear explaination/confirmation of why the key changed...
