No it doesn’t create page overrides, but it creates (vertical) staff spacing overrides, which are visualised with red squares (control points for bot systems: bigger squares, and staves: smaller squares) and the red line (from which you can drag the whole system; all those items are blue when no manual override occurs) in your second screenshot.
The disadvantage to use this method, is that if the casting off changes, and/or those bars move to another page/frame, you loose those spacings. So make your adjustment at the very end of your work, when you know that not much will change.
To make space above specific flow headings, it is better to use Flow Heading overrides, which are more consistent.
Thanks, Christian!
Would it be incorrect for one to generalize, and say that page overrides are created only when frames (of any kind) are adjusted, moved, or created in ways that differ from the applied page template?
Yes, you kindly pointed that out recently. Unfortunately, that’s a feature that doesn’t exist in the Dorico 3.5 that I use! 
Thank-you. I have yet to really get into the proper use of Dorico’s casting off parameters!
A page override will be created even editing/changing/adding/deleting etc.. the text or a token inside a text frame directly on the layout in Engrave mode, instead of editing the corresponding Page Template.
Thanks for this – it’s new to me! Since the page templates that I normally use are the First and Default pages – in which (I think) most text is in the form of tokens – I hadn’t realized that (for example) a custom page template that contains a text frame that contains specific text will reproduce that specific text every time. I had incorrectly assumed that such custom templates would reproduce their text frames, but not their text.
Text frames will repeat their frames. The question is how the tokens within them are set. A text frame in different flows might insert different values for the otherInfo token in each flow.
Thanks, Derrek! Any chance you give an example? I’m having trouble understanding how a text frame can contain a token that would mean different things in different flows.

Info in Flow Other Information fed into a custom heading template.
Many thanks, Derrek!
Is the principle that, since tokens retrieve the contents of specific Project Info fields, and those fields can differ from one Flow to another, a single token can display different content in different Flows without creating a page override?
That’s it.*
