Maybe because advertisers know a lot of people play the opt-in ads without paying much attention to them, ie. we all go into "Ad mode" clicking multiple ads while doing something else. The auto-play ads come one at a time when we are in "race mode" so may be more likely to actually watch them, while waiting for the next race.
