I can confirm this. Only the copyright holder(s) can change the license.

Sublicensing is a different thing; it has to do with liability.

To quote Larry Rosen (legal counsel of the Open Source Initiative)

While we are at it, sublicensing is not without problems. Consider the
following two quotes.

Manesh Pai (an Indian lawyer)

 "By excluding sub-licensing, and permitting re-distribution, the
  developer ensures that there is no privity between himself and the end
  user.  And yes, if the developer permits sub-license, the distributor
  becomes an agent of the developer, and hence the developer becomes
  liable to the user, even in absense of direct contact between them."

Larry Rosen

 "It is best for open source licenses not to be sublicenseable."

Liability is not resolved solely on the relationship between the
licensor and the licensee as mentioned above (called the principle of
privity), but also on payment (called the principle of consideration),
monetary or otherwise. However, it never hurts to be on the safe side,
so I usually follow Larry's advice in my own work.

Well, getting back to the original question, sublicensing has nothing
to do with re-licensing.
