What this article doesn't say is what happens if you don't see both  
file, then what does not 'safely ignoring' the file do? Is it unsafe  
to delete the file in some cases?

And how does the file get put back together? Does the OS know how to  
do this?

"The second new file has the name of the original file prefixed by a  
"._ " and contains the resource fork of the original file. If you see  
both files, the ._ file can be safely ignored. Sometimes when  
deleting a file, the ._ component will not be deleted. If this occurs  
you can safely delete the ._ file."
