Karel your proposal wording still does not quite work!

For example someone could declare Start - A - B - A - Finish where start and
finish are the same as TP B ( or just 10 metres away from B ) - its a double
out and return, a yo-yo!

you still need to seperate any waypoints ( TP's or start and finish ) by 10
km ( or some figure ) and then it starts to get messy 'cos you can't have
the start and finish at the same place!
