Yeah but some centre line depower systems can be just as bad, if not worse, with the kite still pulling hard in a somewhat twisted or crumbled way. The worst situation I've seen is when the lines wrap around the tips and the kite is hovering upside down, like when you hold it walking the kite to the beach. Once it's like that, it's very difficult to recover and sometimes a self rescue has to be performed.
Here is an example of what can go wrong with 4 line depower systems, the most common...
www.seabreeze.com.au/forums/Kitesurfing/Newbies-Tips-Tricks/4-line-kite-safety/The best safety systems are on kites with 5th lines, attached to the centre of the kite, which acts like parking the kite when activated. Even the old Cabrinha left hand depower line along the left hand steerer, allows the kite to park, but it's more by chance than by deliberate design. It's a very hit and miss affair. It doesn't always do that.
