You were a member of both before merging.
After merging the following happened.
If there was a user id similar to yours in ebay.com, then your new id in ebay.in(formally bazee)remained the same with _in1 added to it (most probably).
If you had different email ids for baazee and ebay.com then after merger you have two accounts - one in ebay.in and one in ebay.com
If you had the same email id for both then I dont know what happens.
In baazee you need not sign in just to look. you singn in to buy
