My 4600's have a small plastic handle just under the gear box that moves a nylon gizmo (technical term) and disengages the gear box drive from the ball screw. I don't know if that is a "quick" release, but it does disengage the gear drive from the jack leg. Are you talking about a second release lever that is called a "quick release"?
I haven't tried pushing the leg down with the lever in the released position. If the leg does go down easily, I'll be fairly concerned about an inadvertent release. I'll give that a try tomorrow and see what happens.
If you have 4600's then yes, you can push down on them and they will go down. There is no second lever. The one-way brake and ball-screw design allows for free wheeling down but not the other way. The brake plus re-engaging the lever once you are nearly down makes sure the camper cannot fall. Always run the jacks down a bit more so the square drive re-engages after you drop them. I find this feature VERY nice for putting the jacks down quickly and fairly quietly.
Depending on the lube condition you either can just barely push down or you may have to stand/jump on them. They aren't going to fall down if you leave the lever up, especially if the last thing you did is power them up with the motors. It no more likely than leaving your truck in neutral and having it roll away.
