@Bagginses2Jump attack? I think this stuff is not even needed if you just use saber throw and dodge towards the opponent while he's still being choked and then attack him normally.
The prolonged choke duration card really helps here a lot and optimally you can land like 2 hits already while he's in the air + the additional hit(s) while he's getting up.
The thing when going against Vader is to play with the opponents patience, similar like when going against Dooku.
Most of the time you can manage to bait them to use the ability prematurely, for Vader's middle ability as well as for Dooku's middle + right ability just wait until the effect wears off.
That being said, duels against a Darth Tank in Hero Showdown for example are often just straight boring and repetitive, even if I use Kenobi which assures me that Vader can't use his choke for a while. In HvH I often don't even bother to 1 vs 1 a Vader if possible because it'd take too long and puts me at the risk of getting flanked.
Instead I try to stick with my team, outnumber the rest of Vader's team and then look to fight him with united forces.
I often then just serve as a bodyguard for Han/Leia to put him under pressure and halt his advance.
