Tosafot Bava Metzia 44. On retroactive payments

Can the Rabbi explain the additions to Bava Metzia 34 that explain the difference between challahs for childbearing and challahs for the purchase of fleeces and the birth of a cow in relation to the challah model that you propose in your article?
Tosafot Tractate Bava Metzia, page 34, page 1, 5. I am not a tymeh- tema. It is done as he said to him, "When you steal and pay me, my cow is purchased for you from now on, close to the theft. You may buy it even if it is standing in a lake, as Rabbi Yochanan says in the book of the fallen women (Ketubot 4:22 and 11). Pull this cow and buy it for you from now on, and after thirty days you buy it. Even if it is standing in a lake, and its fleeces and its calves, you do not buy it, even though it says from now on, the purchase is not finished until close to the theft, as Rabbi Yochanan says in the book of the said (Kiddushin, page 60). One came and consecrated it from now on, and after thirty days another came and consecrated it from now on, and after twenty days another came and consecrated it from now on, and after ten days another came and consecrated it from now on, even if they are a hundred, all of them take possession of it, each one with a profit for its fellows. Shebak and Shema 13 I am a violent saint, and since I forgot to mention the benefit, I did not waste it, but here are the fleeces and the children, at least they were given to me at the time of delivery. From now on, I will buy it near its theft in retrospect.
