According to us, the position of the  mark in this bar is an example of a manner of putting markings within their scope, and not at the beginning (as it is currently done), that is in the place from which they should be applied. In this case, the dynamic markings in bars 142-143, placed more precisely, show that the dynamic changes are to be related to the harmonic changes, on the 2nd quaver in the bar. Taking into account the above, in the main text we also put the discussed  mark under the 2nd quaver in the bar.
