Windows 7: Technical Syncronization Question

I copy K:\Games to J:\Games.
I run SyncToy J:\ to K:\ with Echo option and it shows as J:\Games and subfolders and files needs to be sync'ed (copied) to K:\.
The thing is I just copied them from K:\.
Why and how this would happen?

After this happened, I deleted K:\Games, and ran SyncToy again so that J:\Games will be copied (sync'ed) to K:\Games, so that there will be just one K:\Games, but in the first paragraph, why would it want to copy J:\Games to K:\Games even though "Games" folder has just been copied from K:\?



I just didn't understand and wanted to ask and learn about the possibilities.
Thanks.
