They do. They don't run versions that are too old, see below.

Before you contact anyone appearing to run 0.2.2.19-alpha,
check their descriptor and the git part of the version string
therein. Many of those people might run self-compiled versions
of Tor that are more up to date than they seem from the version
string.

Alternatively, some of those relay operators (independent of the
version that is shown in the descriptor) might run a version
provided by their packaging system that backports
security-relevant issues but leaves the rest of the updates alone,
and thus doesn't increase the version.
