It isn't related to IMAP, it's the same for pop3 accounts.
I'll explain it.
The message base for every of your folders is a single file.
When you delete a message, your whole message base should be rewritten
When you delete a second message, the file should be rewritten again
This  means that the whole managing of your message base would consist
of  lots  of  rewrites of big files. Not good for your drives and very
time consuming.
Therefore the index file was invented, it's used for other things too,
but also to remember what messages are deleted.
So  when  you  delete a message, that message isn't deleted, but it is
marked as deleted and the message base will only be rewritten when you
compact it.
That's why you should enable compacting the message base on exit:
 Account -> Properties -> Options -> Compact all folders on exit
As  messages  are  at  first  marked as deleted, you can undelete them
again  as  long as you haven't compacted your message base. And as you
noticed you can toggle the visibility of the deleted messages.
In TB v3 and before 'browsing deleted messages' meant that TB opened a
new  folder  and showed only the deleted messages for your folder, but
the  current  behaviour  shows  them  among  the not deleted messages,
that's more accurate than the old way. (Though it took me some time to
get used to it.)

This  behaviour isn't unique for TB, it's common practice for all mail
clients  and  it's  borrowed  behaviour from databases, who behave the
same way.

It's found in the help file under 'compressing folders', these days TB
calls   it   compacting,  but  in  previous  versions  it  was  called
compressing and the help file wasn't updated.  :-(
