Sometimes it is for aesthetic reasons
So for instance on the Santos Triple 100 it is at "X" because it looks better there than at "VII".

The position of the secret signature is not an indication of production date.
Thanks for the great question.

But I think they might also just do it in 'random' ? Because I'm pretty sure I've seen some at X when the VII was completely free and unobstructed. Or it might be the way they identify the release period too? eg. earlier releases on X, later releases on V...
