Yes, I'm afraid so.

We looked very early on at a design where there was a "context document" as
well as a "context node", and the context document changed when the context
item was set to a node but not when it was changed to an atomic value; we
decided it was so complicated to explain that it was better to take the
simple approach, at the cost of making users do what you illustrate above.
