That is depending on what you regard as the autumnal equinox. The autumnal equinox in the northern hemisphere is in September and it marks the start of autumn. In the Southern Hemisphere the autumnal equinox is in March and it marks the start of autumn. So looking at in that way, you can say yes. Of course those are two different dates on the calendar, so the autumnal equinox in one is happening at the same time as the spring equinox in the other. It is the same equinox, but where on Earth you are, determines which equinox it is. As autumn starts in one hemisphere, spring is starting in the other. So on that basis they don't mark the start of autumn in both hemispheres. It is never the same season in both hemispheres.

What occurs when the sun is directly over the equator?
When the sun is directly over the equator, the Northern Hemisphere has either the Spring Equinox (approximately March 22nd) or the Fall (Autumn) Equinox (approximately September 22nd.) During these events, the length of night and day are both 12 hours long around the world. For the Southern Hemisphere, these are reversed, with the March equinox occurring in the autumn. *At the poles, the equinoxes mark the beginning and the end of the six-month periods of daylight and of night. From March to September it is always day at the North Pole, and from September to March, it is night.

Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere. At that very same moment, it is the autumnal equinox in the southern hemisphere, because as the Sun is moving INTO the northern hemisphere, it is moving away from the southern hemisphere. The September 21 equinox sees the Sun moving south of the equator, so the spring equinox in the south, while it is the autumnal equinox in the North.
