The morphism 0->10, 1->0010 has two limiting words. If the number of iterations is even, the 0-word evolves from 0 -> 10 -> 001010 -> 1010001010001010 -> 00101000101010100010100010101010001010001010, as in A285139; if the number of iterations is odd, the 1-word evolves from 0 -> 10 -> 001010 -> 1010001010001010 (here).
