In plain words
The notions 'mine' and 'this' belong to the yuṣmat side, the 'you' side, and only there — no doubt about it. The notion 'I' is to be taken as belonging to the asmat side. And 'I am this' belongs to both at once.
Close to the Sanskrit
The two notions 'mine' and 'this' are to be known as in the 'you' category alone; there is no doubt. The notion 'I' would be accepted as belonging to the 'I' category, and 'this I am' belongs to both.
