Re-download might happen if offlineimap can't find the cache
("metadatadir"), if it has been deleted or the account name in the
'accounts' setting has been changed.

This depends on what you mean by "safe". If it's about having backups,
see

http://www.offlineimap.org/documentation.html#make-backups-of-a-mailbox

Usually, local deletions are propagated on the remote server so if you
remove emails locally they are deleted on the server too.

It makes copy of the emails via IMAP.
