A good friend of mine works for the CDC and I asked him about this list, he said it is those with serious communicable diseases and the names are supposed to be marked in a way to ensure that they are not viewed as would be bad actors, but rather people who should not fly until they are well.
In other words in theory the TSA is supposed to know that they are on the No-Fly list for health issues and not for nefarious reasons. Though I HIGHLY doubt the TSA is able to understand such distinctions and furthermore capably maintain the list in such a fashion to ensure that those innocent people who happen to get sick are not treated as "baddies".
