To undelete ( or should I say un-mark for deletion) the message you should 
click on "start" column of that particular message.

There are 2 different things:
- mark message as deleted and
- expunge message

Mark message for deletion is IMAP protocol "thing" and it is just a flag for a 
message. IMAP client application (roundcubemail is one of them) can decide how 
to show such flaged messages.

Expunge - that is actually remove message from the mailbox. After the message 
is expunged it is no longer in the mailbox and user can't unexpunge that 
anymore. It is gone.
But, if you configure Cyrus IMAP for delayed expunge (which is default), Cyrus 
IMAP will not remove the message file from the disk for some time. So even 
though user can't unexpunge the expunged message, sysadmin with access to 
Cyrus IMAP server can do that with unexpunge utility provided by Cyrus. 

So all your observations are correct and as the messages were marked forl 
deletion you should see those messages as still being in the mailbox, but 
should not see flaged messages with unexpunge utility, as those messages were 
not expunged.
