As the header suggests, Swipe No Longer Works When Offset And Threshold Are Equal, the swipe closes on finger release. This started happening in the latest release, 2019.2.619.1, previously this worked without issue.
This can be replicated in the SDKBrowser by setting the following in Cell Swipe - Interactive Content example:
SwipeOffset="70, 0, 0, 0"
I have only tested this on Android.
