Q factor definition in the context of individual reactive components 

In the context of individual reactive passive components (e.g. inductors & capacitors), I'm familiar with the following definition: 

The aforementioned definition is presented, in some form, in section Individual reactive components of the article, however, the section Definition of the quality factor has no mentioning of it. Instead, the following definition is presented:

a definition which is practically the same as the other energy-based definition in the section, and furthermore, includes a reference to 
James W. Nilsson's Electric Circuits 1989 edition. I've went through a recent (much newer) edition of the book, and found no energy-based definition of any kind for Q - whether for resonator circuits or individual components.
I therefore tagged the reference as "Failed verification", and additionally, I wonder what is the point of this definition, which is practically the same as the previous one in the article. It seems to me that one of them is superfluous.
