A simple(-minded?) explanation: try instead just creating a Text cell

   This is a test

with _no_ in-line math there. Copy it as LaTeX and look at the result in 
a text editor. You'll see that the text is inside a LaTeX \text{} function.

I presume the purpose is to protect the user from inadvertently pasting 
what should really be text into a LaTeX math expression or display-math 
environment and having it interpreted as a long product of symbols.

And I suppose the underlying reason for having that protection was the 
expectation that users would ordinarily just be copying into LaTeX math.
