I will add "surface tension" as well, like slightly overfilling a glass and the dipstick is the glass but the water rises above the edge |

Most likely the correct answer. |

Sometimes when the oil is undisturbed for a long time it gets tired and it doesn't fully wake up in time to mark the dipstick before it's pulled out. You can knock loudly on the engine block or shout down the oil filler to wake the oil up before pulling the dipstick. Or you can ignore the first reading and take the second, third and fourth as being more realistic wiping the dipstick each time.

Well you have two seals (main and transaxle input shaft), that no matter what you are going to get some weeping of oil get past those or the sealing lips would burn up. Some of that oil gets onto the flywheel and the input shaft, where when the engine is started up the oil is spun off, and gets spread all over the inside of the transaxle bell housing and the front of the engine case. Being that so little oil is spread so thinly over so much area it takes longer for the oil to work its way down to the bottom of the transaxle bell housing, and then drip out of the seam between the engine and transaxle.
