It did take place in a different realm, because Oz is a different realm from the (original) Enchanted Forest.

The third Blind Witch (Hilda), if she doesn't hail from Oz, probably hails from the New Enchanted Forest rather than from the original one, since she's later part of the Coven of the Eight in the New Enchanted Forest.

The first Blind Witch (Miss Ginger) is from the same world as the second Blind Witch, but has no (known) involvement in a Hansel and Gretel story, despite matching the description.
