Poison Resistance and Length Reduction

[Baajikiil]

...however, a 'resist poison' shrine appears to prevent you from being poisoned at all.

I've read that a poison shrine gives you the bonus % poison resist, as well as setting the duration of poison down to 1 frame.

This is right, right?

It just seems that you are immune because it goes so fast. Direct poison like andariel's poison wave should still hurt you a little. Also note the taking the shrine won't change the duration of existing poison.
