Just because you find something in a world that seems inexplicable doesn't mean that Herobrine caused it.
As a matter of fact since Herobrine has NEVER existed in any vanilla version of Minecraft that's not even on the possible causes.
As the OP found out it was just caused by a lava flow.
Note: the configurations of lava flows are affected to some extent on when and from what direction you approach it.
I used to have problems keeping wooden gates on a stone fence I had built until someone pointed out that my 2x2 lava filled garbage pit was too close to the gate and at times set fire to it.
I moved the pit and my gates quit disappearing.

Hi, I was messing around in a hardcore world, and I saw this near 0 0
I don't really believe in Herobrine, but these trees have his name written all over it

Edit: i created the same seed again and the trees were fixed, it seems like it was just the lava pool

What in the original image evokes such a bad meme as Herobrine? Anomalies abound in Minecraft, absolutely nothing unusual here.
