Actually it's not wrong.  The POD just doesn't match the code,
unfortunately. :(  (feel like opening a bug?)

Yes, the different score set is used to avoid any biasing by the Bayes
system for as to whether or not to autolearn, but there's also a check
of the Bayes score that was applied (rule score not bayes probability)
via https://issues.apache.org/SpamAssassin/show_bug.cgi?id=2865.  In
short, if the message seems to strongly be ham or spam, don't
autolearn it the other way and let train-on-error happen if it is
actually wrong.
