It's a good method. My favorite, at least for knives with a kick, is to hold the knife normally, then bring your thumb back and press the tab. For non-Gunting knives, you press the tab and the left liner between thumb and forefinger. for the Gunting, you simply press your thunb to the right (slightly harder, since there's less counterpressure). The kick will fall on your index finger, then you withdraw your fingers, rotate the knife, and press the blade home with your fingers on the outside of the blade.
This works well for all knives with a back lock, but it does pose the possibility that the blade will scrape your fingers as you withdraw them. If you're careful, this possibility is very remote.
For the Lil' T, the method you illustrate looks very safe. Lemme get my Salsa and try it...
... chalk up one more way to easily close a Compression lock!
Just make sure that you aren't pressing on the blade before fully disengaging the compression lock, or you'll put undue wear and tear on the tab.
