Well, isn't it just an extra jump check that's "Can Only Jump To Same/Higher/Lower Regions" at the same time?

No it's not.
But if you want to achieve the result of "Can Only Jump To Same/Higher/Lower Regions", just set the jump check to "Can Jump". This will be the same as your qoute. Player will be able to jump on any region, higher/same/lower.
That is why I asked what you are trying to do, because if I could know that, I may have better chance helping you, as so, you will have better chance being helped.
