Because redundancy doesn't technically exist in these terms. "Redundancy" is a reason for a fair dismissal. That's all. If you are dismissed by reason of redundancy then there is Statutory (or Contractual) Redundancy entitlement, which is tax free up to £30k. Notice pay would be listed separately as it is subject to tax. It sounds like they haven't decided whether to return you to work prior to the termination - there is no right to be paid notice pay and you can be required to work. So you need to ask them for confirmation about that - you won't be paid notice pay unless they don't want you to work your notice.
