That's what is generally voiced, but it's not that easy. The top of the rim is actually drawn inward from string tension over a very long period of time, although not to the extent of the bottom of the heel moving outward. Adjusting the bottom coordinator rod to pull the rim inward then results in the classic "egg shaped rim". It's not a lot, but it doesn't take a lot to effect tone.

The other thing to consider is there are different ways that are used to join the neck to the rim. As an example, dowel stick attachments don't flex up much at all if they were constructed and assembled properly to begin with.

Another factor is banjos have relatively low string tension when compared to a guitar, so the forces don't operate in the same manner we associate with the guitar.
