The file is shipped in assets/, and you cannot readily serve an asset
from a ContentProvider. It is tons easier if the file is a regular
file on the filesystem. So, onCreate() sees if the file was already
copied to internal storage, and if not, makes a copy from the asset.
The check for file existence should be pretty fast. Besides, this is a
book demo, and so I routinely cut corners in the interest of reducing
lines of code count to make the samples more focused on the problem at
hand.

In your case, the file already exists on the filesystem, so you can
probably just junk my onCreate() entirely.
