I see your follow-up in which it appears this may be attributable to
separate shell processes, but in addition please note that typeset -g
does not actually declare a "global" variable (despite the mnemonic).
It merely declares a "non-local" variable.  The actual dynamic scope
of the variable will be the nearest surrounding scope in which that
parameter's name is already defined (even if both defined AND unset;
in the unset case it may become set again, but it's scope remains).

Thus "typeset -g name" declares a true global $name only when there
is not another $name already declared (or $name is already global,
of course).
