(info "(elisp) Property Search") has the following:

     -- Function: previous-property-change pos &optional object limit
         This is like ‘next-property-change’, but scans back from POS
         instead of forward.  If the value is non-‘nil’, it is a position
                                 ^^^^^^^^^
         less than or equal to POS; it equals POS only if LIMIT equals POS.
                                    ^^

I don't understand the second sentence. What "the value" stands for? If
it stands for LIMIT, what "it" stands for?
