COMMENTS

The morphism 0->11, 1-> 010 has two limiting words.  If the number of iterations is even, the 0-word evolves from 0 -> 11 -> 010010 -> 11010111101011 -> 01001011010110100100100101101011010010; if the number of iterations is odd, the 1-word evolves from 0 -> 11 -> 010010 -> 11010111101011 , as in A285414.
