Good question. It must be due to the reason you listed above... how so, not sure. Two methods to put slightly more fluid than what will fit at the fill plug level:

1. Elevate one side of the car (either fill plug side or rear axle of vehicle).
2. If you're using a pressure bleeder to fill the transmission like a Motive, you can put a paper towel around the fill plug hole to prevent most of it from dripping out. But you'll have to be ready to put the plug in quickly to prevent too much ATF from coming back out once you're done filling.
