You are confused with the difference between probes and match lines.
There are only a few dozen probes, but they can match thousands of
different services. If you run with --version-intensity 9 -d2 you should
see all the probes being sent.

$ grep -c ^Probe\  nmap-service-probes
60
$ grep -c ^match\  nmap-service-probes
5489

See http://nmap.org/book/nse-vscan.html. Scripts in the "version"
category are loaded for version detection. The scripts have to be loaded
to get their portrules.
