Actually, no, that isn't the focus of the preso.

The first four will not work against a DDOS attack

This is incorrect - suggest you read the preso.

and the last one just kills the patient so he does not infect other patients. 

S/RTBH - as opposed to D/RTBH - doesn't kill the patient.  Again, suggest you read the preso.

There's been a lot of discussion on this topic on NANOG, suggest you take a look through the archives.
