You're not dreaming; I had similar difficulties when I was trying to get
VM's digest parser to skip backward over consecutive message delimiters.
I was using the `+' operator.  I eventually had to use a while loop
because I couldn't persuade re-search-backward to match more than one
delimiter per call.

It's almost as if re-search-backward works by moving backward a
character at a time and calling re-search-forward with the appropriate
arguments, although I'm sure that's not quite the way it's done.
