Credit limit confusion

I have a tata neu plus HDFC card, which earlier had a limit of 50k. Then I got HDFC freedom card, which was put on a shared limit with my earlier tata neu card. Now, I got a limit increase on my tata neu plus HDFC to 57k. Now do I have seperate limits on both cards, as the limit showing on tata neu is 57k and freedom card is 50k? Or is it still a shared limit?
