I agree. The online AIM also indicates the underlined text. See
http://www.faa.gov/ATpubs/AIM/Chap5/aim0504.html#5-4-9:

"a. A procedure turn is the maneuver prescribed to perform a course
reversal to establish the aircraft inbound on an intermediate or final
approach course. The procedure turn or hold in lieu of procedure turn
is a required maneuver when it is necessary to perform a course
reversal."

Thus, if you're already inbound on the final course (assuming you're at
the altitude the procedure requires), no PT is required.
