OK, without looking into it very deeply, I have to admit that I can't see
a real problem.  You just added 1000 identical lines directly to the
history file and read it into a fresh bash invocation.  Wouldn't you
expect that they would all end up in the history list?  If you don't want
to execute each line from the history, you should be able to just go to
the end of the history with M-> or edit the line you're currently on and
hit return.
