The Ants Go Marching

Three ants are walking in the same direction. The first ant has two ants behind him, the second ant has one in front and one behind, but the third ant has one in front and one behind too. How is this possible?

The ants are in a circle. Lets say the ants are A, B and C. A has has B and C behind him, B has A in front and C behind, and C has B in front and A behind.

When 3 ants are walking in a circle, at any moment, the ant in front is walking in a direction 120 deg relative to the center referenced ant and the one behind is walking 120 deg off also, so none of them are walking in the same direction.

In theory, if you have 3 2-dimensional ant walking on in a straight line on a 3-dimensional sphere would mean they are walking in the same direction, thus if they are spaced equally far apart from each other, it would fit your definition since these 2-D ants would have no concept of height or change in Z axis direction.

To all of the people that day the ants are walking in a circle, this is incorrect because the riddle says that the wants are walking in a line. I think that they are walking on a ball or a spherical shape of some sort.
