If those are the only two actions in your flow, then it wouldn't be creating an infinite loop. The first action is also a OneDrive action, so unless you have shared the folder TEST with someone, nobody but you would be able to update the files located there. Based on your image, this flow will trigger when any file in the folder /TEST is updated and is not specific to one file. I would open this location in your OneDrive and look at the Modified and Modified By values to see when the most recent file was updated.
Maybe you have another flow that is creating or updated files in this location and that is causing this flow to trigger.
