Notice how Laurie is playing with the ring Jo gave him while saying this? He played with it for like 5 seconds. This is the moment he really considers his feelings for Amy. As he was calling her beautiful, he changes the ring's position as if it is no longer important to him. He thinks about Jo and his feelings towards her and starts to think that the love he has for Jo is different as he realizes he may have feelings for Amy and cares for her differently.
