DND 5e (2014) Elven Accuracy Macro's using the queryadvantage attribute

I found a Macro that changes the query advantage attribute of 2014 dnd sheets posted on this forum 6 years ago by a user named Mohkan, while in theory it adds elven accuracy as an option it doesn't actually  reroll the lowest of the original 2 dnd, it rolls 1d20 and also rolls 2d20k1, I am trying to wrap my head around whether that is logically/mathematically relevant. For example, in my testing the macro rolled 5 on 1d20 and 10,9 on 2d20k1 (rerolling the 9).  If you believe it to be an inaccurate representation of "triple advantage" and have an idea for a fix please let me know, I don't want to cheat myself/my table. {{query=1}} ?{Advantage?|Normal Roll,&#123&#123normal=1&#125&#125 &#123&#123r2=[[0d20|Advantage,&#123&#123advantage=1&#125&#125 &#123&#123r2=[[1d20|Elven Accuracy,&#123&#123advantage=1&#125&#125 &#123&#123r2=[[2d20k1|Disadvantage,&#123&#123disadvantage=1&#125&#125 &#123&#123r2=[[1d20}

rolling 1d20 and rolling 2d20k1 then keeping the highest of the 1d20 and 2d20k1 is going to result in the same final d20. 15, 10, reroll 10 get 5 = 15 15, {10,5}k1 = 15, 10 = 15  15, 10, reroll 10 get 18 = 18 15, {10,18}k1 = 15,18 = 18 flipping that around: 10, 15, reroll 10 get 5 = 15 10, {15,5}k1 = 10,15 = 15 10, 15, reroll 10 get 18 = 18 10, {15,18}k1 = 10,18 = 18 With that said, if you were to use the 2nd d20 for some reason (not in the rules, but houserules exist) then it would result in different results and would not be applicable.
