Because an offset/ptr follows a too simple pattern and potentially there could exist specific bugs patterns where the overwriting data and the marker match.

The xor-with-a-constant operation has the interesting property of keeping the variability, it would just made the ptr values not look like ptrs.

In other words if for instance you have an array a with 10 elements, the probability of your code generating the value a+10 is higher than (a+10)^0xdeadbee5.
