1. Use the Asumptions option of Integrate
2. move the xup == yup constraint to the Assumptions
3. use Simplify. if you do not use 2. above, use FullSimplify

Integrate[
If[x >= y, 1, 0] 1/((1 - xup) (1 - yup)), {x, xup, 1}, {y, yup, 1},
Assumptions -> {0 < xup < 1, 0 < yup < 1, xup == yup}] // Simplify

returns 1/2
