Where two roads are multiplexed, it looks like one of the refs is

Is this done 100% consistently?
99.99% consistently, and that might actually be understating it. Anything
that is missing the brackets can be considered a signage error (I can only
think of one instance) and not worth constructing an entire data model
around.
I've always read the brackets to mean 'leading to' or 'via' not as being
shared. From the Highway Code: "Motorways shown in brackets can also be
reached along the route indicated."
