Files Uploaded using Mapped Drive (UNC) to SharePoint Document library Putting a copy in Recycle Bin , odd SharePoint Behaviour

Question

Hello All,
One of my client reported a strange behaviour.
Client mapped SharePoint document library to local share(UNC, NetWork Map Drive). Opened MS Word on local machine ,saved it to the share on his local machine. The document is saved successfully to SharePoint document library. But at the same time he can
see a file with same name in Recycle bin and the size of the document in Recycle bin is <1k.
Does any one know whether it is expected behaviour, why SharePoint putting this 1k file in Recycle bin?
I tried the same thing on my Dev Environment for both SharePoint 2010 and 2013, in both environments the behaviour is same as my client experience.
I have seen in forums some other people also experiencing this odd behaviour, but no one knows why.
any info on this much appreciated.
Regards,
Andrew

Hi Andrew,
i tried in my environment for 2010 and 2013. The issue doesn't occur.
Here is what i did.
1, Create a new mapped drive(\\servername\DavWWWRoot\Shared Documents) for document library
2, New a Word doc and input some string, save in the mapped drive.
3, The doc exists in the document library, but no file in Recycle Bin.
Did i miss something?
Regards,
Tom
