If I constrain an expression holder after we assign to it a chunk of the CVX variable, will it be equivalent to constraining that chunk ?

Your question is not very clear. You need to be more specific.

Is that what you are asking?

variable x

y = x

0 <= y <= 3

constrains x to satisfy 0 <= x <= 3

is the following equivalent:

variable x(n)

expression h(n)

minimize norm(Ax-b)+lambda*norm(x,1)

and

variable x(n)

expression h (n)

h=x;

minimize norm(Ax-b)+lambda*norm(h,1)

Yes, equivalent …
