Update dynamic tags from a dropdown

Following the old video from Gaby: https://www.youtube.com/watch?v=DNiyikDO0TU

My issue is, she uses a count of names in the database and runs it against the count of values of the multi-dropdown, so that if the latter exceeds the former, it triggers the event to save the new tag. Makes sense.

But in my test view, the multidropdown evalutes to however many tags are in the field, not the option list. So it evaluates to 0. If I type in a custom tag, it evaluates to 1. But it should evaluate to the total number of options, which would then exceed the number in the database by 1.

Why is the value count only the field and not the multi-dropdown element itself?
