Since you already noted that the earth is a sphere, has it not also occured to you that if one goes north around the world, one could just keep going, without end?

BUT--you are not always traveling north. Once you hit the pole, you will begin to travel south. Hence--north DOES meet south.

Now, if you travel east, there is never a point on this earth at which you will start to go west (without changing direction).

Distinction without a difference, I'm afraid. One could still just as easily keep heading north (or south) without changing directions. Travel in a static vector is not in any way dependent on the poles.
