Red button, or blue button

pokemon-x-y

So Team Flare decided to set their plan into motion:

Activate the ultimate weapon to wipe out all who aren't part of Team Flare.

Naturally, I went to stop them, but now I have to choose between pressing a red button or a blue one.

The scientist I just defeated told me that one of the buttons will activate the device, while the other will shut it down, but he didn't tell me which.

Knowing the Pokémon series, I doubt I can make a wrong decision, but I still get the feeling that choosing one button or the other may result in subtle-to-moderate differences in the game later on, such as which Legendary I will meet where, or similar.

What will happen if I decided to press the red button? What will happen if I choose the blue button? Or does it really not matter at all?

Either way, the ultimate outcome is the same, as

The machine was going to be activated anyway, whether by you or them. He himself says he would have activated it anyway had you pressed either button.

There doesn't appear to be any difference in the later game based on your choice.
