It keeps the file handle to the inode not the filename so when you mv 
filea fileb the listener is still writing to the inode which now belongs 
to fileb so if you want to move it you need to do the set listener.
On the other hand if you cp filea to fileb then the listener is stilled 
pointed at inode in filea so if you intend to truncate then the cat 
/dev/null cleans out file a whilst all contents up to that point are now 
in fileb.
i think most unixes allow 
> filea 
to delete its contents

HTH

Cheers

Why is it necessary to null out the file? Does LSNR keep a open file 
handle
open to it?
