This would be true for a static system with the climbers hanging (note, no net movement, the only force is weight) in free space. The system for a slackline is significantly more complicated, involving slackers falling (a dynamic process involving acceleration, and thus more force), and also needs to factor in the load multiplication across the span (see the tyrolean force calculator posted abvoe).
