1990 civic hatch pcv system

Is it normal for the pcv box to have two seals. I'm wondering if the previous owner added one for extra security.

The engine is a 1.5L.

Please see picture.

Arrow points to seal in question.

Thanks.

Oh man, I thought I had answered this one earlier this week... Maybe I was at work and got interrupted or something. Sorry.

It's supposed to only use the single O-ring that is in the groove.
And the parts catalog only shows one O-ring for that part.
