Yes and no. For some Office documents, the software makes shadow copies. These are termed versions and are created during edits and saves. Even if the saved document is recycle deleted the versions remain and can be recovered. Also what the recycle bin does is strips only partial file information making the site on the disk available to be written over. It does not erase the data entirely. This is why you can recover Recycle Bin deleted items, if you act quickly, using software made for this purpose. In fact you never really erase anything via deletes. Software that removes or destroys data over writes the disk clusters with random 1's and 0's. The closest you can come to erasing a disk is to format it.
