Idk, man. This one is set up differently than other abilities that would need multiple context values.
For example, T3's unique zeta, the Armor Pen is put in Context value, then the Armor Pen is modified, then the Res Pen is put in Context value, then the Res Pen is modified. In that case, either they are separate Context values or the same is overwritten by the second query.
Vader's speed boost unique works similarly to T3's unique. The number of Jedi enemies is put in Context value, speed increased, then the Rebel enemies, then speed increase, etc.
Zam unique, same pattern.
I didn't spend long, but I couldn't find an example where there are clearly 2 distinct Context values nor could I find an example of Context values being added together.
