Exactly.
And LoadVMMaker.st script placed there exactly for eliminating the
problems when you unable to determine which VMMaker version works with
given sources snapshot.

This is a link between git snapshot and sources which stored outside
of it (in SqS/VMMaker or elsewhere).
And by having this link, we can reproduce an image and then generate
source files, so we don't need to put a generated sources under
source-control anymore.
