Share facts #2

Hello. Recently I've made an off-topic post about some cool facts that you noticed and made you laugh. I declare a part 2 of this new series! Here is mine:

1.e4 e5 2.Nf3 Nc6 3.Bb5 is the Spanish or Ruy Lopez

But why 1.e4 e5 2.Bb4 is called the Portuguese opening if it's the same signature move?

Bb5, I just did a mistake when writing, and I can't edit it because it was 2 days ago.

I declare this topic closed, because there already is one.
