Counterbalancing conditions

I watched your youtube video but I have trouble understanding

in this case do I have to do two qualtrics surveys to be able to send from pavlovia end link ( completed url) to the next quatrics block ? or to FinalBlock in uncompeleted Url

the idea is to do
Block1: link to Exp1 (condition1 pavlovia) ==> return to Block2 (Quatrics)
Block2: link to Exp2 (condition2 Pavlovia) => return to BlockEnd (Quatrics)
with the files result1.csv and result2.csv
