Off the cuff hypothesis: 

Perhaps for the one lighting, it becomes Shabbos immediately, so the
hadlakah is for Shabbos and there is a beracha. But for others in the
house, they likely don't take on Shabbos until davening, and therefor
they enjoy it on YT. Which would be enough to matir her lighting them. 

But I have no source.
