No, because egen total does not accept a varlist. It accepts an exp, as does generate. This is the source of your problem.

total(exp) (allows by varlist:)
creates a constant (within varlist) containing the sum of exp. Also
see mean().

As it turns out, egen [var] = rowsum([varlist]) is equivalent to
egen [var] = total([varlist]).
