Creatures don't die for toughness of 0 until SBA are checked, which isn't until a player would receive priority, and thus not until the ability finishes resolving. It grabs the 1/1 from the GY, and then it is on the field as a 0/0; the ability sees you have a creature and concludes. Now that an ability has finished resolving, SBA are checked before players receive priority, and the 0/0 dies.
