You are using the word "substitution" instead of "assign-define". That's the way it works or known to work. It has to be this way because in general the definition will carry parameters that have nothing to do with the symbolic, like in the DE Laplace solver, thus not losing the generality of the setup.
Your example [if the one catched from Rich] is a non sense. You must realise that if you reinject the solution of one variable vs the other, the back substitution returns the value you have solved for. Mathcad 11 and probably 14 does exactly what you are asking for. You can plug manually, the solved argument. But that is totally useless to plug back the solving argument as it will return the value solved for.
The general case works like it has always been working. A CAS like Mathcad obeys the rules that apply and not any rules that don't apply. The rule you are trying to apply is not a rule.
