This effect depends on the particular application. Some applications require to be uninstalled before they can be reinstalled. This happens in particular when the application uses local data, since this data is not cleared when you install the application over itself. In your case, I can see from the log that the Web Resources Integrity test failed. The log does not show why, but my guess is that it might be caused by data that the old installation left on the device.

Due to iOS limitations, the Application Center Client cannot automatically uninstall the application. There is no API for uninstall, unless you use an MDM solution. Hence, the Application Center Client simply installs the application over itself without uninstalling it before.

In order to be on the safe side, I recommend to uninstall the old application explicitly before you install it again.
