In the cell diagram for chapter 14 #29.c, the cell diagram goes Pt(s) l H2(g) l H+ (aq) ll Fe2+, Fe3+ l Pt(s). Does the order of the iron ions within the brackets matter?

In these electrical cell diagrams, the reactant of a half reaction is usually found on the left, with the product being found on the right. I do not think that the fact that the two irons being in the same state changes this. So, the Fe2+ should be put to the left of the Fe3+.
