Property between XorSum and Sum of segment

Правка en2, от prudent, 2018-06-27 13:05:19

Why if xor sum of segment is equal to sum of segment, this condition is also satisfied for all subsegments of original segment?
I know that it's true when all bits in numbers are unique, but is it the only case when it's true, and if it is, then why?
