Note I'm using upper_bound bellow. The link you provided says:
Change 25.3.3.2 [lib.upper.bound] paragraph 1 from:
-1- Requires: Type T is LessThanComparable (lib.lessthancomparable).
to:
-1- Requires: The elements e of [first, last) are partitioned with respect to the expression !(value < e) or !comp(value, e)

So value is on the LHS and the element at the RHS.
