I couldn't find the link to the paper again but here is another link. Basically what they are saying is the condensate line is usually very close to your evaporator coil. Bleach and Vinegar are corrosive so vapors can be sucked into the evaporator coil via the fan and or if you drain clogs and that mixture gets into the evaporator coil pan, can cause corrosion and premature evaporator coil failure. That's basically it. On older systems the construction may use thicker copper and other metal so it can take longer for corrosion to affect the coil. This is why most manufacturers are Now saying just use hot tap water once a month to flush out your condensate line.
