He is simply pointing you to a location where you can read more on the topic.
If anyone signed up for the library today with the expectation of receiving the PowerGallery, then we will gladly refund and cancel the library membership that you mistakenly purchased.
I can see how it could be misleading for someone unfamiliar with the library and what it includes, but really our intent was to send an email promoting the current specials... not to deceive. The PowerGallery and Library happen to be the two items we are promoting at the moment, so they shared the same email.
No need to read any more into it than that, but you should always read and understand the terms when purchasing anything. Marketing materials will always point out the most positive and beneficial aspects of any offer... they are short and concise by design and really can't be expected to include all of the minute details.
The Library is a relatively new offering and I guess we still have some lessons to learn about how we should and shouldn't market it because of its unique qualities. We will learn from these mistakes and correct them as early as possible.
