UPDATE: Explained... Unexplainable: Windows Phone and Windows 8 apps being shared?

Hey everyone! So I logged on to my Windows 8 PC today and went to my apps in the Windows Store, and strangely enough I found fruit ninja there as purchased but not downloaded. Interestingly enough, I never purchased the app on Windows 8 due to the ridiculous price, and that I already had it on my phone. Also I noted that it says it was purchased July 8th 2012 which is pre Windows 8 release and I am pretty confident is not the date I purchased this app on my Windows Phone. Has this happened to anyone else? Any explanations for this phantom app? Not complaining but confused. UPDATE: It appears that the free app is related to the release and consumer preview, nothing to do with Windows phone. Thanks for the input guys!
