The commands are of quite different nature I think.

`edebug-eval-top-level-form' instruments and evals a form _in_ Edebug,
while `edebug-eval-top-level-form' evals a form from inside edebug, in
the _outer_ (i.e. debugged) context - without Edebug stepping.

Or with other words: edebug-eval-top-level-form is for instrumenting and
starting edebug.  `edebug-eval-top-level-form' exists only for the
purpose that C-x C-e behaves as expected - you don't want it to evaluate
stuff in the inside context, the edebug session, where lexical bindings
would not be visible etc.  That would not be very useful (unless for
debugging Edebug maybe).

Try to use them and you'll see how that makes sense.
