It is uncertain what led to the difference in the position of the 
indication. It is unlikely that we could be dealing with Chopinesque proofreading of GE1; moreover, there are no traces of the indication having been moved in print. However, the interpretation of this mark makes us consider the version of the editions to be more accurate. In A the mark is also written in the solo part, although repeating it only for its last chord does not seem intentional. Therefore, according to Chopin, must have referred to the connecting passage marked as Tutti as well, which is confirmed by the full version of the Variations – the orchestral Tutti starts already at the beginning of the bar, whereby marks are written in the parts of wind instruments at the beginning of the bar, and in the ones of string instruments – on the 2nd quaver. When copying probably from the parts of the wind group, Chopin did not notice a possible ambiguity resulting from the lack of synchronisation of this indication with the beginning of the Tutti, which in the version for one piano is marked only just on the 2nd quaver in the bar.
