Absolutely.
And Platinum members can name someone to get Gold status right away.
Therefore, a family of four may enjoy all the perks (mainly lounge) even flying Y for a private trip.
As a personal remark, it makes sense to aim for status if you fly Y, but, you need to fly a lot. So, if EK is a natural choice, go for it. If not, it's not worth it.
