Foundyalenny

So this weird thing has happened multiple times on my second play through of RDR2. In my first play through i had one horse that i bought from the stables that i used for the entire game intill the start of the epilogue. In my second play through I've found random horses with the exact likeness of that same horse and even having the name i had given it. Their not bonded to me, their random ones. Anyone have any ideas why this happens?
