I know this is old, but I solved the jetpack problem for project ozone. It's simply that an XOR gate means you can't do both of the prerequisites to get it, you have to only do one. XOR means if there is two of the same input from both (true true, false false) there is no output. I don't know why they would design it this way but it is what it is.
