Maybe because THE SUFFOCATION HAPPENED ON THE BOTTOM BORDER.

Yes, I checked the code. The last piece of the amoeba growth from its upper sibling. So it is growth through the bottom border to the first line that's why it gets the "already scanned" flag so the last piece was skiped from scanning in the next frame. And another pieces can't growth so the amoeba suffocated into diamonds.  
  
Open border side effect.
