It's just marketing. Saying something different to try and encourage you away from what you normally drink.I remember when they introduced the round teabag then the pyramid shape teabag back in the 1990's. It was supposed to allow the leaves more room to move, or something. Didn't taste any different to me.
I bet they spent a lot of money on r&d and had some smart fellows working on that. I mean, working on the pyramid teabag is inventing something. Not exactly the Wright brothers though, is it?

But it has no affect on the flavour.
