In FE there are no ties sustaining the upper notes of the octaves in bars 73-74 and 75-76. According to us, the most probable explanation is a misunderstanding at the time of changing the original abbreviated notation of the octaves with the use of 8 under the upper notes for regular notation. In CLI the octaves, written in the described brief manner, are not sustained at all, which most probably is a mistake.
