It's to do with the way the keys were signed at the time they were

There is a "default certification level" option that can be used either
on the command line or in a config file - normally GnuPG will ask you
for the certification level when you sign a key, but the default /can/
be used if the right options are set, and /will/ be used at the time of
key generation.

        Death to all fanatics!
  Down with categorical imperative!
