A show is a fleeting moment in time, not designed to be repeat listened and analysed. That's why many bands hated bootlegs back in the day, and many artists don't want people to record shows on cell phones.
I can't see any reason why Mark would want to release multiple live shows, especially unedited and unmixed.
As an artist you want to be represented by your best work.
The Sydney BIA show and the Basel OES show were never assumed to be widely repeat viewed or even VHS recorded. This was before the internet and Youtube. The uploads infringe copyright and so do any bootlegs.
OK, as musicians we've learned to live with modern taping, both VHS and now cell phones, but it does mean some musicians who are afraid of being analysed for mistakes will play safe every show, instead of going for it.
