EXAMPLE

As a word, A010060 = 0110100110010110100101100..., and replacing each 0011 by 0 gives 011010001011010010110010001011...

MATHEMATICA

s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {1, 0}}] &, {0}, 9] (* A010060 *)

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"0011" -> "0"}]

st = ToCharacterCode[w1] - 48  (* A284622 *)

Flatten[Position[st, 0]]  (* A284623 *)

Flatten[Position[st, 1]]  (* A284626 *)
