No, this is not correct. It depends on the kind of conflict. If you have 
not conflicting changes in your local copy those will be merged. There 
will be a G letter besides those files in the "svn up" output. No error 
message. If the change is conflicting it will ask you what to do.

If the file has no change in the repo but has local changes local 
changes will survive. If you instead always use "svn checkout" then yes, 
it will overwrite changes.

If subversion did such a thing(destroying local changes silently) it 
would be a very big problem for developers.
