It does seem wrong.
hobbit:~$ mkdir /tmp/x && cd $_
hobbit:/tmp/x$ touch Foo_01 Foo_02 Foo_11 Foo_12
hobbit:/tmp/x$ GLOBIGNORE='Foo_0*' eval 'echo Foo*'
Foo_11 Foo_12
hobbit:/tmp/x$ GLOBIGNORE='Foo_0*' bash -c 'echo Foo*'
Foo_01 Foo_02 Foo_11 Foo_12
hobbit:/tmp/x$ GLOBIGNORE='Foo_0*' bash -c 'GLOBIGNORE=$GLOBIGNORE; echo Foo*'
Foo_11 Foo_12
