Ah yes, in some situations order can indeed buy production, but in others production 'buys' gold. Sometimes your capital only troops are much better than what you can get at other castles, so you use less of them, so you spend less gold and have less upkeep. Sometimes (as I mentioned before) you can get heavy infantry instead of medium saving gold and upkeep. Sometimes your initial expansion (before you can get up additional castles) is much faster, gaining you more income than order would have gotten you.

You're missing my point in pointing out that you can buy production by spending gold...everybody knows gold can buy production which is why gold is king. My point is to remember that production can also 'buy' gold and sometimes that is the more efficient way to go.
