What is the significance of having a point on my primary Sketch at the Planar Origin?

OK ..I might be confuse ...
Lets say for example we're drawing a square or rectangle...
I wouldn't start my corner at the origin. Rather I'd try to center it so the origin was in the middle of my box. Then I would constrain it so that the origin is centered around the origin, without actually being attached to it ...
It might affect a 3D printed file, where you would have to manually move the part to the center of the bed. Although I'm not too sure, as I only have a rudimentary knowledge of the operation.
Inventor (like most things) has a certain workflow to specific tasks or goals. Some tasks can be achieved in more than one way. Others require a specific workflow to achieve the end result.
Making a part that isn't centered can also affect the ease of constraining a part in an assembly... or vice versa. It all depends on what you want to accomplish. Just think ahead about how the part will be used later on, or it could mean more work for you.

I ask again, what difference does that make?
If you really really really want to know the answer to your question - attach your *.ipt file here.
The principle can best be illustrated with your actual files you have created.
Using Centerpoint Rectangle rather than 2-point rectangle reduces the numbe of dimensions needed.
I never use zero (0) magintude dimensions - use coincident constaints.
So one reason to anchor symmetrically about the origin is to reduce work (I am incredibly lazy).
Your extra work on left, my lazy work on right.
