shrshifts your bits to rightushralso shift right, but fills up the most left bit with zero
If you're only doing bit shifts on positive values, there is no difference. If you're also doing it on negative values, there is a big difference.

In this case, the ushr will flip the left most bit so you're now having a positive value.
