@katrin When I fix problems with my own photos, I have often seen that a few in the beginning of the sequence have been way off and some times the GPS has just jumped for off the correct location for a few images. If you just cut the sequence, you will have a few images that are placed in the completely wrong place.
But because you save the messages from the sequence_cut user, there is a record and if people want to fix it in the future, it is possible.
I can imagine that everybody have a lot of work to do, and I did not imagine any other fix at this point
