It's not the location, it's my decision. When the EA is generated it first excludes all blocks that are left alone. Again, because my initial idea was to be able to keep some blocks around like this for "later use".
Now I don't like this concept very much, because when I left few blocks like this, I just forget what was their idea. So I am thinking to make those blocks to run and keep blocks for "later use" somewhere else, in some isolated field... if anyone needs that at all.
Also, I am thinking to remove block numbers. Now what matters (when connected in parallel) is the number of the block - the one with lower number will run first. But what if the block on left (or top) runs first? This is something that I didn't tried yet, but I will eventually do.
