IIRC, it was a response to laws like the United Kingdom's RIPA which
allows the authorities to demand encryption keys from users. By
separating encryption and signing into separate subkeys, and making the
signing subkey the 'master' one, it allows users to divulge encryption
subkeys to the authorities when required, then immediately revoke those
encryption subkeys and resume encrypted communications with others.
I may be in error.
