It doesn't matter what the arrangement of the portals in the nether is. Zombie pigmen have a chance to spawn at a netherportal in the overworld without having gone through the portal from the nether. (So this mean they will also spawn if the nether is not loaded/generated)

One thing that might work against you on MineRealm is the fact that MineRealm is set to easy. I believe in the video he said he was playing on hard difficulty. Here's a quote from the MineCraft wiki.

Zombie Pigmen rarely spawn near portals in the overworld, but only one at a time. They spawn twice as often on Normal difficulty as on Easy, and three times as often on Hard difficulty compared to Easy. No other mobs can be spawned by Nether Portals in this way, in any dimension.

Expect less than a third of the pigmen you see in the video.

Yeah, I understand now. I could not watch the video but I do remember reading about pigmen spawning in the overworld a while ago after one of the updates.

I would consider building one of these myself but I need to re-build my village and start/finish my iron farm. God job prodigy.

I like the idea. Too bad I object to large ugly structures fouling my lands... Oh well. I just had an idea for the perfect automatic melon farm.

I was thinking of putting one inside of a tower - no exposure to the ugliness unless you're inside
Alternatively, you ought to be able to fit one almost entirely underground, if the bottom is built near bedrock.

I should look for it.

There are a few technical issues you'll need to consider to get a gold farm working effectively in MineRealm, but I'll let you have the fun of working those out for yourself

Sneak peek at MineRealm's first overworld gold farm below...

How far from your location do the pigmen spawn?
