As someone that works in the game industry and interacts with programmers and artists (not only graphical art, I am also counting here writing, music, etc...) daily it is BLARINGLY OBVIOUS that both skills require certain brain patterns.
Although there are some rare people that are both great programmers and great artists at the same time, usually the person is a programmer, or an artist, they might know skills of the other side (example: I am a programmer, but I have a design bachelor's degree, and know how to use lots of artists tools and correct art made by others, but I would never call myself a good artist) but they are clearly one thing, not two.
This usually is also reflected in their behaviour, for example programmers frequently act in more logical or common sense manners (or sometimes in a extreme logical manner that go against common sense, but still logical), and can be viewer in some ways as "boring", and tend to prefer things rooted in reality.
The artists are not uncommon to do things that are unexpected, or to like outlandish stuff, for example when playing an RPG with extensive character customization you will usually see the programmers min/maxing the stats or trying to go for realistic stats, and outfit the character in realistic clothes, or the best equipment in terms of stats. Now when you look at an artist character they frequently are different, for example you might see a orc magician, or a space marine with low accuracy stats, high charisma and that paints his armour pink with yellow dots.
Then when we get to real work, the need for talent is obvious: Innate programmers frequently make boring art, IF they can make good art at all. Innate artists sometimes can make some code, but usually it is badly engineered code (prone to bugs and breaking), and that is, sometimes, most artists can't code at all, you can try to teach them all you want, and they just don't understand, even those that might grasp the syntax still end never getting past basic logic.
Of course, sometimes you find some people that are exceptions, for example the Falanghe brothers:
Felipe Falanghe is the creator of KSP, he, and his twin brother, studied with me at university, they are clearly artists, during university their highest grades were always in pure art related classes, they could make amazing drawings, and they had a band and were both fairly good singers and guitar players, yet both of them decided to learn Flash and Unity coding, and although their code was frequently broken, hard to read, confusing and had huge amount of memory leaks, clearly it was possible to do something with it, since KSP is a success, and Felipe Falanghe started coding it by himself in Unity.
