The Scrum Guide - Sprint Review Meetings

Hi,

In the Scrum guide which is supplied as a revision aid for the PSM I Exam, there is a section headed Sprint Review, and in the first paragraph there is a sentence stating:

'Based on that [what was done in the last Sprint] and any changes to the Product Backlog during the Sprint, attendees collaborate on the next things that could be done'.

There is also a bullet point stating:

'The entire group collaborates on what to do next, so that the Sprint Review provides valuable input into subsequent Sprint Planning Meetings'.

I would have put these activities down as taking place during Sprint Planning meeting(s).

Can anyone explain the point that I am missing?

Thanks.

Grant Sugars.
