I didn't know there were 50/50 and normal vortexes. I always thought a vortex was something where you're forced to guess right or you stay in the loop. If the only options that force you to guess end the vortex is it a real vortex?
A vortex doesn't have to include true 50-50 guesses. The end situation just needs to loop into a forced mix up situation. Conditioning plays a larger role when there is no true 50-50.
To answer your question, the vortex only refers to the looping portion of the mix up. The vortex ends when the loop ends.
Scorpion has a true vortex. However the actual vortex portion of the mix up is dependant on conditioning.
If you were to rate mix up games in mkx
1. 50-50 vortex. True guesswork. Unreactable looping low and overhead starters that lead into another mix up
2. Vortex. Reactable looping resets w low and overhead combo starters.
3. Low, overhead, throw. Single hit mix ups. No loop.
4. Low, throw.
