Yes, that is how it works.
On a side note: Oddly enough, with CustServ's other ruling, using the Frost Weapon's at-will ability doesn't give the power the keyword, so if not for this keyword inheritance, you could be doing all cold damage with a power with only the fire keyword... does that sound a bit stupid to anyone else?
On further reading, my excerpt is out of context. The excerpt comes from the description on using powers of items. So, item-keyword inheritance comes from the keyword of the item power used, provided the item power and the class power are used at the same time.
Looking at Flaming Weapon, it has two powers, one at-will, and one daily.
The daily power modifies what happens as you hit with another power. Ergo, it is used at the same time as that other power, thusly, the -resulting effect- inherits -all- keywords. Notice, the language does NOT say the -power- gets the keyword, but that the -result- -has- the keyword.
Awesome.
The other power, the at-will one, is a free-action as well, and modifies the result of actions taken. The only difference in terms of timing is one is triggered by an action you take, and the other has no trigger at all.
Therefore, if the at-will ability is active when you're using another power, they are therefore an item power and a class power being used at the same time... and therefore... the effect inherits the item power's keyword.
So, regarding the use of a cold weapon and another weapon on something wintertouched, with Twin Strike.
This is where inheritance gets a bit tricky.
Wintertouched triggers when you use a cold power on a vulnerable creature. That's important to note: When you use a cold power.
In order for it to trigger, you must use a power... ANY power, with the Cold keyword.
So, twin strike... it has the Martial and Weapon keywords. You're using a frost weapon and decide to use it's at-will ability to make it deal cold damage. The other weapon is non-energy damage based and irrelevant to this discussion.
The attack you make with the other weapon does not deal cold damage, nor trigger Wintertouched, because it is not Twin Strike that gets the Cold Keyword.
The attack you make with the frost weapon -does- deal cold damage because of the effect of the weapon. However, it does not have the Cold keyword, because you're not using any power -on the enemy- with the Cold keyword. You've used it on the weapon itself, not the enemy. This means that Wintertouched won't trigger, because you never used a power with the Cold keyword on the enemy.
But what if you use the daily power?
The daily power applies an effect -to the enemy.- It even has the word 'target' in it so you know that it targets something and otherwise behaves -exactly- like an attack power in that regard.
So does Wintertouched trigger? Yes. Not off of Twin Strike itself, but off of the Frost Weapon daily power that targets it.
Do notice this however......
If the feat triggered off being affected by a cold -effect- or by cold -damage- (like vulnerability does) then in -that- case, both instances would trigger it without a problem.
Another example, in a different direction.
Let's say I used the daily power of a Duelist's Weapon with Brute Strike.
Brute Strike has the Reliable keyword, so if I miss, I recharge that power.
However, if I miss with a Brute Strike with the daily power of the weapon active, the weapon's daily power doesn't gain the Reliable keyword and recharge. The total -effect- is Reliable (if somehow a monster had Vulnerable 5 vs Reliable, that might matter) but Reliable doesn't go to the individual powers making up the effect.
