Only one creative from a line item can serve at a time.
ONE_OR_MORE
Any number of creatives from a line item can serve together at a time.
AS_MANY_AS_POSSIBLE

could mean anywhere from one to all of a line item's creatives given the

All or none of the creatives from a line item will serve. This option will only work if
served to a GPT tag using SRA (single request architecture mode).
