Why can't you differentiate tokens by their position on the board?

Once a token is dropped it will occupy a set of coordinates on the board, which will probably be a position in an array. Since no two tokens will be able to occupy the same set of coordinates, wouldn't it just be a lot simpler to identify tokens on that basis?

Location would not make a good identifier because the token ID's are assigned before they are placed on the board.

I understand that. But why would tokens ever need to be distinguished before they are played? I guess that was my mindset. But I'm still not very far into the course so I suppose I will see.

The tokens are identified by owner and index. The owner aspect will be important to determining if adjacent tokens contribute to a winning position. This information will be used in addition to the location they are placed in during game play.
