Those actually have the same levels in the same order: a < b
Possibly, this brings the point home more clearly
(Notice that alphabetical order is largely irrelevant, so all of these level orderings are equally possible:
a < c < b < d
a < b < c < d
a < b < d < c
b < a < c < d
b < a < d < c
b < d < a < c
