It will be interesting to see what the Dev's say about this. I guess I'm still using old habits from my Pixhawk days. 
Considering that you must do full down and full left (not just some down and some left), I wonder if everyone does it correctly.
It may be easy to test, remove the props, put the Solo in various flight modes, perhaps turn it upside down, and then hold the throttle full down and full left, then see if you got a 'disarm' command. Perhaps check the logs to see if a disarm came in, or if the thing used crash detection or land detection to shut down the motors.
Thanks for looking into this, as I said, perhaps I'm learning something new. It certainly wouldn't be the first time!

I don't think the logs show the reason for disarming other than crash detection which shows up as an error message. There isn't anything I'm aware of that would say disarmed by pilot command vs disarmed by landing detection. I'm pretty sure everyone currently doing down/left in loiter and alt hold are seeing it disarm by landing detection and it's coincidence they happen to have the stick all the way left for no reason. I'd been doing it myself until recently when I realized all this.
I just did a search for this thread by typing in landing
it is amazing how many posts have come about botched landing since P2P took the time to write this.
This is why the people complaining about no printed manual crack me up
If you aint going to read the on line manual
or great posts like this
You sure as heck aint going to bother to read a paper manual

In all seriousness, no it isn't the best. But that doesn't mean it's wrong, or you shouldn't do it. The automatic landing on Solo (and any other Arducopter powered drone) is fantastic. But there are scenarios where it isn't wise, and scenarios where you will need to do something else if it doesn't work.

I've had several flips on landing by holding throttle down and waiting to disarm they have been on uneven ground. Is it because of the uneven ground. Both situations it seemed to try to take back off both times I was in stabilization mode and did land mode would it be better to land in Manuel if ground is uneven or to hand catch then disarm ?
I learned something that may seem obvious to some, but I don't recall seeing it documented anywhere:
If you have a flipover on landing, be sure to power down the Solo before using it again. Twice I've tried taking off without doing this, once resulting in another flip on take-off and a second time with an unstable take-off.
