No. PlacelessSetup modifies the global component architecture registries.

That has nothign to do with PlacelessSetup.

PlacelessSetup creates no content. buildSampleFolderTree simply creates 
a folder structure, it is up to you (or your test) to either store it 
somewhere or not. Tests should obviously never store anything, which is 
why even functional tests don't open the standard ZODB storage, but an 
in-memory one.

Note that using PlacelessSetup is often overkill. Its widespread usage 
is rather historical. In most cases nowadays, it's enough to

* register the components you need with zope.component.provide* during 
your test setUp

* clean up using zope.testing.clean.cleanUp() in your test tearDown
