I see where you're coming from.
We represent it as a guide, not a hanger. It doesn't put any stress on the waste pipe. Ultimately it's up to the inspector, and from my experience they tend to agree that it meets code.
Not to offend, but I'm sensing a little back pedaling here. The image that you posted clearly shows it as a support and the support is dependent on the waste pipe and therefore the waste pipe is under stress. Changing the word to describe the action does not change the action.
