The following section in the documentation assumes that the reader understands the importance of 'Have' lists in Perforce:

https://www.perforce.com/manuals/jenkins/Content/P4Jenkins/populate-forced-clean-sync.html?Highlight=%22Populate%20have%20list:%20%22

Populate have list: Overwrites the Perforce "have list".

Suggest that it is changed to include a description that includes the impact. For example:

Populate have list: Overwrites the Perforce "have list" that records which files have been synced to the workspace. This is usually relevant when you are not force syncing and want the next sync to only transfer changes since the last sync.

Note: I am not a documentation expert but you get the idea .
