For someone coversant with TERPS - not very.  For someone who meets
the knowledge requirements for the instrument rating but not much more
- pretty reasonable.  Note the context - the runway numbers are
changed (increased).  I can easily see how someone might think that
this means the final approach course should also be adjusted, and the
direction and magnitude of the adjustment are consistent with the
runway change.

Not exactly plain English, is it?
