Hehe! That's true.
Given this input:
foo
bar
It produces this output:
(foo)()
()(bar)()
()
This happens because it's reading one line at a time. The regex matches
the word, then the empty string before the newline, then the empty string
*after* the newline.
If you have it read in the whole input as one string you'll get the
same behavior that occurs in BBedit:
perl -pi -e 'BEGIN { $/ = undef } s/(.*)/($1)/g' test.txt
