I would say was intended, you can confirm if you have an older build by checking the script to see if the variable is there.
the variable to check is there, not for the initial jasmine and rebecca creampie tho....rebecca even says she's on pill before but her newer scene has the creampie variable
so it seems the dev has started using these variables recently (maybe 2-3 updates prior...so it could be patreon influence or now was just the time the dev felt like having the variables worked)
also the game is using new variables to check for newer creampies
eg. judie has both judiecreampie and judie3creampie as variables
tho this maybe for checking whether mc came in her during 3some as the reason for the 3 being there in the second variable
same with iris, she has variables iriscum and iris3creampie
