The weird thing is that in all their raging maximalism, they don't include Portugal and Brazil in their Spanish empire, even though the Iberian Union was a thing for 60 years.I think it was just some coincidence. But depicting colonial empires seems to be a difficult task, especially when the map maker wants to cover several centuries at once.
Next map (also from reddit) very related:

I'd also love to know exactly when they thought the Spanish Empire included East Anglia, Greece, Nigeria, Namibia, Yangon and the North Island of New Zealand.
