If you haven't set $MANPATH manually, then man and friends guess it
based on the value of $PATH. From get_manpath() in the source (and read
/etc/manpath.config for man_db.config here):

 * For each directory in the user's path, see if it is one of the
 * directories listed in the man_db.config file.  If so, and it is
 * not already in the manpath, add it.  If the directory is not listed
 * in the man_db.config file, see if there is a subdirectory `../man' or
 * `man'.  If so, and it is not already in the manpath, add it.
 * Example:  user has $HOME/bin in his path and the directory
 * $HOME/man exists -- the directory $HOME/man will be added
 * to the manpath.

man-db. (I'm the maintainer.)
