Was this a bad idea ?

On my 1998 Subaru Impreza AWD I bought some used tires and got them installed from the tire guy. The thing is all four tires are a different brand. The front two tires are Bridgestone and Fuzion tires which both have the exact same tread. The back tires are Toyo and Kumho which have the exact same tread. Also, all four tires are the exact same size. Will these tires work good? Because the front two are basically bran new and the back two are only maybe a year old.
