The kernel just installed in the previous step might taint itself for reasons unrelated to the issue the reader used when he started this process. Make sure the reader catches this early, as this is the area where it really matters. The former check was just ensuring the reader notices early if his kernel is tainted, e.g. before he does more complicated and dangerous things in this process.
