Set-PnPListItem -UpdateType option "SystemUpdate" and "UpdateOverwriteVersion" behaviors are not match the document.

Hello, this is my first post.
Now I suspect the document is mis-described. But I'm not sure. What would be the expected behaviors?

On the document about Set-PnPListItem,
https://pnp.github.io/powershell/cmdlets/Set-PnPListItem.html
for -UpdateType option 'SystemUpdate', it described
"Sets field values and does not create a new version. Any events on the list will trigger. The "Modified By" and "Modified" fields not updated and can not be set." .
However a flow, which has ”When an item is created or modified” trigger, was not triggered when I excuted Set-PnPListItem cmdlets with -UpdateType "SystemUpdate".
For -UpdateType option 'UpdateOverwriteVersion', it described
"Sets field values and does not create a new version. No events on the list will trigger. The "Modified By" and "Modified" fields are not updated but can be set by passing the field values in the update. HINT: use 'Editor' to set the "Modified By" field.".
However a flow, which has ”When an item is created or modified” trigger, was triggered when I excuted Set-PnPListItem cmdlets with -UpdateType "UpdateOverwriteVersion". And the "Modified By" and "Modified" fields are always updated without explicitly setting the field values.

My environment is PowerShell 7.4.1 and PnP.PowerShell 2.4.0.
