It's natural to Delphi users, nothing in general and inconsistent with
normal client behavior.

Execute block uses question mark, normal parameters uses question mark.
But in Delphi they are replaced.

Your example also shows how confusing it is:
----------
S = 'INSERT INTO TTT VALUES (:a, :b, :a)';
EXECUTE STATEMENT (:S) (CURRENT_TRANSACTION, CURRENT_CONNECTION)
----------

Three parameters, two names, and two values...

I'm against this syntax.
