ICICI Credit card Limit query

Hi, I already have ICICI Card with 4.6 Lakhs limit. I applied for another pre-approved ICICI card and it is showing limit of 1.1Lakh. Since, limit are shared in ICICI, will the limit of my earlier card would also reduce to 1.1 lacs or it would remain same as 4.6 Lacs. Anyone having experience , please share.
