Great vids, thanks, but that safety feature is such a handbrake it's crazy. You've already had to deal with what many less-educated people would consider death machines, namely chainsaws. So if you can handle one of those safely, you most definitely have the requisite skills to handle a kinetic without needing the lawyer-induced safety feature that is the two handed operation. Seriously, if you ever can, please get on a Super Split (or disngage your safety feature) for a wee while, especially having built the experience you now have with a kinetic, and let us know what a PITA it is going back to the relative slowness of your one and that you really didn't appreciate how good the splitting could be until you got behind a Super Split.
If you want, I'll bet you $20 that if you got on a well set-up kinetic that didn't have that safety feature, and spent a bit of time getting used to the rhythm you can generate with one, you'll be seeking to disengage that safety feature on yours.
