According to the Rashbam, the Gemara is discussing an external border. It is only Batel to the field if it does not have its own independent significance, Chashivus. Therefore, we say that when there are dates there, if he did not specify it in the sale then it is assumed that he left it for himself, because something which has independent value is not automatically included. However, if the border is small or insignificant, then we do not assume that the seller left it for himself, since a seller does not leave for himself something insignificant.
