Not combined, since that could violate the standard by forcing the use
of an algorithm that the recipient is unable to use.  Instead, the
personal lists are used to limit what the keyholder may request.  In
the example you give, the result will be the empty set since there are
no common algorithms chosen.  This will result in

An easy way to think about the personal prefs is as an additional
recipient that doesn't actually get the message, but does have
preferences that must be taken into account.
