Cell Diagrams in 14.15 and 14.17 6th Ed

For these answers, I am confused on why for 15 the Ni(OH)3(s) and Ni(OH)2(s) is only separated by a line, whereas in 17 MnO4-(aq) and Mn2+(aq) has a comma separating them?

When two aqueous solutions are in the same cell they're split with a comma while if they're other phases they're separated with a line.

Right, but Ni(OH)3(s) and Ni(OH)2(s) are in the same phase still and is still separated by a line?

Solutions of the same phase are separated by a comma and arranged in the oxidized, reduced order

Yeah, if theyre any other phase except aqueous they are split with a line. I think it's done like this cause if its aqueous theyd mix if water was added while if they're in other phases they dont necessarily mix directly so a line is given instead.
