Very much so. Gametap is simply acting as a distributor. The preamble even says: "Cyan Worlds principal and franchise co-creator Rand Miller on the recently launched massively multiplayer title". At least now when I look.
Cyan Worlds
was about to close their doors, and forewarned their employees that they were going to lose their jobs, but with then the deal with Gametap came along. I believe one of Gametap's founders was once an employee at Cyan.
Edit: There's also the second to last question:
Jonric: Would you care to tell our readers a bit about your company and the team associated with this project?
Rand Miller: We are developers, Cyan Worlds. We're located in Spokane, WA. I am CEO of the company and work closely with the design team here. We've got a core group of employees who have worked here for as much as 14 years, on the entire series of Myst games.
