Yes. That's what the tcpdump is showing.

As I understand it, the receiver can advertise a new window if the 
available window increases by one MSS or half the buffer space.

In this case, it seems to send the 1st window advertisement when the
window increases by 1 MSS, and then more whenever the window size (roughly) doubles.

In this case, the receiver (apache-server) is a Red Hat ES3 installation which
is based on the 2.4.21 kernel, and the sender (tomcat-server) is a Red Hat ES4
installation, which is based on the 2.6.9 kernel.
