my understanding on svn switch

when i switch to some location of my subversion reposory using svn switch,
the following things hold:

any new files/dir from the repo location will be added to my working copy,
if they are not present in my WC
any existing files/dir (that exist both in the repo and WC) will be
overwritten in my WC, therby overwriting any changes
any files/dir present in my WC, but not in the repo location, will be
deleted from my WC

Can any one confirm this understanding of mine?
