Orchid Confusion

Hello everyone!

This orchid is the only live one I've ever owned and I was nervous about getting it in the beginning.  But, now 2 yrs later, it has proven to be hearty.  It is now blooming for the 3rd time.  

I moved it next to this wall just so you could see it better. It normally sits by a window.

What I'm confused about, though, is it's root system.

Here are the roots at it's base. 

And here is another root system at the top!  What????

This didn't exist during it's last blooming cycle.  And of course, with it's additional set of roots are additional leaves too!  

Does anyone know if this is normal and am I supposed to leave it or cut it off and replant that section?

These are the beautiful blooms hanging off to one side.

This is where it normally sits........beside my bathtub.

But, I have a feeling that those leaves and roots shouldn't be at the top of the plant too.

Would love any advice you have to share about orchids.

Thanks for stopping by!
