That is probably because it dates back to a time before HOME was
set to the target user by sudo.

As of 1.8.28, the current description is:

    If enabled, sudo will set the HOME environment variable to the
    home directory of the target user (which is root unless sudo's
    -u option is used).  This option is largely obsolete and has
    no effect unless the env_reset option has been disabled or HOME
    is present in the env_keep list, both of which are strongly
    discouraged.  This flag is off by default.

I think that is much clearer than the wording in previous versions,
though I don't object to making some small tweaks if you feel it
is necessary.
