I thought with "reversible" they meant that a number falling 50% and then rising 50% afterwards, it is the same number, which is not true.

10 * 50% = 5

5 * 150% = 7.5

50% of 10 is 5

10% of 50 is 5

Not sure if you're saying you got it.

Yeah the correct term would be "commutative" as someone already pointed out. Meaning the order doesn't matter when considering multiple percentages. E.g 50% of 73% of something is the same as 73% of 50% of that same thing
