OK, I see - you are expecting the var file to be written immediately
but this is not a guaranteed behavior.  It gets written at various
times but not after every block.  It is certainly written at
shutdown so the coordinate systems are saved.

Is it true that the machine motion is correct in all cases, including
when setting an active coordinate system, and the system origins are
saved when EMC exits and then restored on the next run of EMC?

The var file is a way for the interpreter to save some values - it's
not meant for "human consumption".  If you need to interact with the
var file directly, you can be sure of getting consistency by doing
it when EMC is not running.
