My two cents...
On the following thread, Jomoj and Jan seem to have nice solutions. It is true that the 5th wraps when the kite tumbles down or hits the water, not when you release the safety. So releasing the safety will prevent the 5th from wrapping.
I ave about 150 outings with the 5th element bar and no real wraps. I had the kite passing through the lines with a 5th caught with a steering line. this happened a few times. For some reason I never flew the kite that way, I just wrapped up and let myself drift to shore (5-10 minutes) or walked back (shalow water or frozen lake)
4 line kites are not fool proof, the bandit isin't either. I launched a buch of them and saw many tangled pulleys... The metal pullies are heavy and swing and wrap around the lines and get stuck together.
SCBkiteboard mentionned in its test that leashing the kite on the mini 5th may end up in an unridable mess-Cannot comment on this personnaly, this should be true for any kite leashing on both front lines but I have not ridden anny except the Evo, but the evo does not fully flag out.
I think the best way is to keep tention in the lines, if you screw up then activate the QR so it will not wrap, if too late and wrapped, then the pressure has to be removed from the 5th so you don't tear the kite so pull a back line real hard so you hold the kite by a tip.
