I'm trying to figure out how to use context options in a geometry ROP, but it's not quite working the way I expect.

I'm setting the option in LOPs, and the geometry ROP is upstream in a sopcreate node, and I'm using python nodes to check that the context option has been set, however it doesn't seem to get picked up by the export nodes.

Scene attached. Pretty sure I'm doing this wrong, any pointers on the correct approach would be appreciated!
