Paraglider wings are designed to gain altitude in good conditions & glide in normal circumstances. In contrast, parachutes are generally made to reduce altitude.
Some time reducing alt is necessary during flight. Cloud sucking is one of them. B- Line stall is a maneuver that reduces alt. very rapidly. This will transform a Paraglider canopy to the parachute. I feel this technique should be included in a basic training of flying the Paraglider.
B-Line stall is performed in two stages. First by having the breaks in hands, identify B-line metal link in both risers, then in proper positions & conditions SYMMETRICALLY pull them up to ear level. There will be strong resistance of the line & it requires tough forces. In the second stage, the line will be easily pulled down to the shoulder. Canopy stops flying forward, this will result to overshooting the pilot forward and backward. Soon it will be stabilized and at the same time the pilot feels falling down & reducing alt.
Exit from the B- line stall is performed in two stages. First lines are released SYMMETRICALLY half way slowly, and then let it go back to its position. At this moment wing surge forward & gain speed. Surge control is required.
I do not recommend doing a B-line stall by any one for the first time. This should be done under direct supervision of a qualified instructor.

Nice clip.
As you state on 'recovery' the key is a fairly rapid final release of the B lines to avoid the risk of the glider remaining in a parachutal stall.
If parachutal post-release one option is to press FORWARD both A risers and smoothly ease off as you regain forwards flight.
(Note: 'Old School' recovery is to use brakes On.... Hold a couple of seconds... then quick release to surge the wing.)

Good site/condition to explore our wings..
Well done Farshid a.k.a "HurryUp Doc"
