It seems perfectly logical to me ...

One of Warlock invocations you can pick is to cast False Life on yourself ... allways on level 1, but for free!
What purpose would that serve if it would be overwritten by Dark One's Blessing after first kill? smile
Sure. It's just that in PnP players are generally left to manage their own characters. So if they hadn't read the rule that temporary hp don't stack they wouldn't find out until they tried it.

That's why you can swap out an invocation when you level up.
