Here's an excerpt from ox-beamer.el documentation:

;; - Headlines become frames when their level is equal to
;;   `org-beamer-frame-level' (or "H" value in the OPTIONS line).
;;   Though, if an headline in the current tree has a "BEAMER_env"
;;   (see below) property set to either "frame" or "fullframe", its
;;   level overrides the variable.  A "fullframe" is a frame with an
;;   empty (ignored) title.
;;
;; - All frames' children become block environments.  Special block
;;   types can be enforced by setting headline's "BEAMER_env" property
;;   to an appropriate value (see `org-beamer-environments-default'
;;   for supported value and `org-beamer-environments-extra' for
;;   adding more).

In particular, "All frames children become block environments". So in
your example Third-level is a block environment and Fourth-level is
a block within it. There's no flattening going on (look at the tex file
to convince yourself).
