But that simplified view is wrong – the XOR is performed on a , not on the data in the binary. The real condition is that after XOR’ing each entry with the corresponding digit, the last 8‑byte value after the table (which is not part of the table) must equal the magic constant. Since that value is static, the only way the comparison can succeed is if the loop does not alter the pointer that is later used to fetch the final constant. In other words, the loop must exit early or skip the final compare .
