I don't think I understand what you are running into
for me just a simple display flag on the Clip and Paint node selected I can paint interactively



or if you want to display it at the same time, 3D/Display flag workflow seems to work for me

you can use Paint 3D COP and plug your original heightfield into canvas

What does the other artist have to do to get the last update?

it's common for houdini to pick up the otl changes automatically, especially if the user is interacting with the node or do stuff like bypass/unbypass, so in theory they can just continue working and the node should break, I mean update, at some point

to force it they can do Assets/Refresh Asset Libaries

usually it's a good practice to do updates on a bumped up minor version number or a dev branch and when you want them to test/use it they can version up or switch to that version, that can avoid broken scenes and other issues like renders changing/breaking mid sequence etc
