I am not sure what "original" spell really mean. Would it make a difference if it said "base" spell? Would it mean the same? Was it intended to mean exactly the spell before previously applied metamagic or is it just a word tossed in? What if you "first" apply Twin Spell and then the other metamagic (I don't know if every mm feat refers to the "original" spell, you know this better than me)?
If that was intended, for what purpose? To prevent exploitation? So what about a Twinned Cold-Substituted Fireball: to me it should deal cold damage both times, if it dealt once cold and then fire it would be generally better (and you would be effectively having the Energy Admixture effect without the feat, IIRC).
As a side note, again about stacking metamagic in general: the rules seems to become more and more cautious (I mean, since 3.0, then the errata/faq/sage advice, and finally 3.5) about stacking mm. The original 3.0 rules were very linear. Later someone thought that is should be less than linear otherwise it's too good; but increasing slots is NOT a linear cost IMHO, since increasing e.g. a spell from level 1 to 2 is less "expensive" than increasing it from 2 to 3. Applying the same mm twice or applying different mm one after the other (and not always upon the "original" spell) has a cost that is already in general higher than the benefit.
