Are you actually sure you mean "USB tethering" to sync a Windows app with Android? I generally understand that term to mean "sharing the phone's internet connection via USB", which isn't the same as just allowing file transfer between the computer and phone. It's not obvious to me why you'd need USB tethering to sync an app, but of course I don't know what this app does.
In any case I agree with others: that screen is saying that some other device, presumably your PC, ran up your data usage via either USB tethering or WiFi hotspot.
Computers generally only use one internet connection at a time, e.g. if I plug my laptop into the wired network in my office it uses that instead of WiFi (which it is also connected to). So the question is, if you connect to both, which one will it use? And if you do have USB tethering running but the ethernet connection taking precedence, it will certainly switch to using the USB internet connection if the ethernet is interrupted.If the computer is also connected to the Internet through Ethernet → modem → Internet, doesn't Windows use that connection instead of the smartphone + data plan when it's connected to the computer through USB tethering?
