1. No. From ":help <afile>":
<afile> when executing autocommands, is replaced with the file name
for a file read or write
<abuf> when executing autocommands, is replaced with the currently
effective buffer number (for ":r file" and ":so file" it is
the current buffer, the file being read/sourced is not in a
buffer).
IOW, for :read and :source, <abuf> is the current buffer and <afile> is not.
2. What do you mean, unique? A file can be opened in several windows, but the
buffer will normally be the same (I'm not sure about the case when a file is
opened by different names, owing to soft -- or, worse, hard -- links).
Best regards,
