If you get beaten down to 200 health by some mix that includes magic damage and Hexdrinker goes off, then Karth can wait for the shield to expire before ulting you, as the original comment said.

If Garen spins you down to 200 and you take no magic damage in the process, then if Karth tries to ult you, Hexdrinker will activate and you might live.

Usually you'll take both kinds of damage, so a good Karthus who notices you taking Hexdrinker should change the timing of R so that it goes *after* Hexdrinker expires. If that extra couple of seconds lets you do a lot of damage, then this at least costs him something, but if you've already run away and your shield has already triggered, then you're in trouble.
