Needs comments here.

Word boundaries are visually ordered. It is ordered from right to left for LTR block, and ordered from left to right for RTL block. (as comments in nextWordBreakInBoxInsideBlockWithDifferentDirectionality and previousWordBreakInBoxInsideBlockWithSameDirectionality). 
this returns the last word boundary in this ordered list.
