Syncing is not magic that guesses what you need. It has a policy of 
operation. Owncloud uses a very simple one, but it is clear: it is time 
based, so yes, it will wipe all your local data if the files on the 
server have recently disappeared.

However it is true, that the sync client should notify you before big 
deletions, tell you how many local and remote files you appear to have, 
and offer you the possibility of a one way sync to repopulate the other end.
