You will get the 100% Plat bonus instead of the 25% Gold on your next flight. The only other significant difference than I can think of would be if your next flight were international in coach. If Plat, you could get club access. If that is your situation, I would think if you printed out a copy of your statement and asked the lounge dragon nicely, you would get admitted. If that is not your situation, I can't see where it will change your life in any significant way, so just kick back and enjoy the ride. Plat will come to you, you don't have to chase it.
