This is the current feature, nested $[] are not allowed, so effectivelly
the first variable inside $[] is not expanded, but all others are ok.
This is because $[pict-0-$[page.nx] is considered as one $[] variable.
Generally, the rule is: only valid and currently defined $[var.name] are
expanded by fvwm, all other $[] strings are left as is.
Anyway, if you add additional dollar at the beginning:
Echo $$[pict-0-$[page.nx]-$[page.ny]]
it will be expanded as you want (I hope so, because you didn't say what
you want to get):
[FVWM][Echo]: $[pict-0-2-3]
