Section 7.2 says:

In case of SRP-ID-number wrapping, the last
   SRP-ID-number before the wrapping MUST be explicitly acknowledged, to
   avoid a situation where SRP-ID-numbers remain unacknowledged after
   the wrap.  This means that the PCC may need to issue two PCUpd
   messages on detecting a wrap.

It should say:

In case of SRP-ID-number wrapping, the last
   SRP-ID-number before the wrapping MUST be explicitly acknowledged, to
   avoid a situation where SRP-ID-numbers remain unacknowledged after
   the wrap.  This means that the PCC may need to issue two PCRpt
   messages on detecting a wrap.

Notes:

incase of srp id wrap, once PCC detects it, PCC needs to issue PCRpt message not PCUpd message.
