What does one do if he catches the imam in bowing and there is a worshipper to his right?

Question:
In his second question, he says: If one person was with the imam at the beginning of the prayer, and then a third person arrived, and he wanted to catch up with the rak'ah while the imam was bowing, does he stand to the right of that ma'mum, or does he pull the first ma'mum to him and remain in the second row? May Allah reward you with good.

Answer:
He bows with the first person, either to his right or to the imam's left, so that he does not miss the rak'ah. Then they both move back behind the imam. If he arrives while the imam is bowing and there is one person with him, he has a choice: if he wishes, he lines up with the person to his right, and if he wishes, he lines up to the imam's left, because the right side is occupied. Then, after rising, they move back. The sunnah (recommended practice) is for them to move back behind the imam; this is the sunnah. Yes.
