Unfamiliar use of interval brackets

Hey, I was wondering if anyone could clear up for me what would generally be meant when you say that a certain value has to

"lie within the strip ] x , y ["? What exactly does it signify when the brackets are in the opposite direction as compared to how you would indicate a closed interval from x to y, [x,y]?

Aha, so it's just an open interval? Thanks, that helps a lot to get that cleared up!
