Allocations instrument ref count issue

In the Allocations instrument under the reference count column, there is an entry after autorelease and release entries where the reference count becomes 3… I don’t understand how the ref count went up to 3 from 1 since ref count increases or decreases by 1 at each step. This doesn’t seem right. I have even checked the code using stack trace… I just don’t get it. I’m a first time user of Instruments app and Allocations instrument… The rest of the allocation/deallocation entries above the selected one are clear to me… The selected entry is where the problem starts. Am i interpreting this the wrong way or what? By the way, the image in the link is of Touch Tracker from previous chapter being run in Instruments. Pls assist.
