Look at the documentation for (\.),
http://www.jsoftware.com/help/dictionary/d431.htm. The left argument
to the suffix adverb \. is expected to be a verb or gerund. As such,
(]\.) produces a valid derived verb that applies right-identity to
suffixes of 'abcde'. Another example,

<\.'abcde'
+-----+----+---+--+-+
|abcde|bcde|cde|de|e|
+-----+----+---+--+-+

where <\. is a derived verb that boxes suffixes.

The domain error is due to the left argument to suffix (\.) being a
noun rather than a verb. By way of analogy, consider the difference
between,

'abc'/
|domain error
|       'abc'/

and

   ]/
]/
