Yes, it does.

As the OP says, "The variable (id) is only going to be equal to one of
the five each time it reaches this point" - so I have a pre-condition on
which I am allowed to rely. Nevertheless:
id < 1 || id > 5 || (set $piece(^|"app"|global("index"),"^",id * 2 - 1)
= $horolog)
will add the range check for you. Less elegant, of course.
