*Spoiler* Not understanding how something works

How were there 2 green balls near the end of the game?

There weren't?

It's complicated! In short: "orbs" are worlds in their entirety, so if you're looking at the green orb while you're inside of the green world, the orb must contain itself. Therefore, the outer green orb that you see will have a smaller green orb inside of it (along with smaller orbs of any color that are currently inside the green world). Full explanation of the events that happen in-game below.

There are 3 types of portals in Cocoon:

• The "pool of water" ones, where you place an orb in the center and then can enter the orb by entering the reflective liquid around it
  
• The "appendage" ones, which are the smaller circles with wavy "appendages" that take you back to the previous world you were in (two exceptions to this rule at 5% and 65% but that isn't relevant to your question)
  
• The tall vertical gates, which, when unlocked, let you walk directly into a world without any warping whatsoever

At 94%, you enter a tall vertical gate which leads to the green world while you're CARRYING the green world, which is contained within the red orb. When you set this red orb down and then enter an "appendage" portal within the green world, you're taken to your previous world, which was red. Here, you find the green orb which you had set down earlier, but red just entered green when you entered the tall vertical gate, so you'll now find that the green orb within the red world also has red inside of it! You've created a weird scenario—the green orb is in the red world, and the red orb is within the green world. They both contain each other.

Next, while you're in the red world, you pick up the green orb (which contains red), and use the "appendage" portal to be taken back to the green world. Both the red and green orbs are now located within the green world, which means that the green orb you're carrying now has a both a red orb and a green orb inside of it! You didn't "create" a second green orb, the orb is simply inside of its own world. If the green orb IS the green world, and the green orb is inside of the green world, then the green orb is inside of the green orb.

To be more specific, the 'appendage' portals take you out of the orb you are currently in, rather than to the one you were previously in. This sounds the same but is slightly different, as it doesn't need exceptions for 5% and 65%.
