Yes.

Those numbers come from svn "$Id:...$" stuff in the manual's source.
Why they happen to have those strange values I don't know.

Anyway, the manual was updated more than two years ago, and that
version (available from CTAN) is pretty much definitive, since
development of PDFTeX has stopped. The website was updated one year
*before* the manual, which is why it contains an outdated manual.

Best,
