This is peculiar, because I don't believe we've ever written it out with the upstream libexec path. Yes, the examples file shows it as libexec, but we've written out "Subsystem sftp /usr/lib/openssh/sftp-server" for new installations since 2005.
Is it possible that you had hand-edited your sshd_config at some point?
