That's the old way (where old < IBA 1.2).

I can dig out more emails on this and any recommendations.

In the older versions of IBA, the bit was inverted due to some language
ambiguity. It was supposed to be global.

I would think we want to be compliant with the IBA 1.2 definition but
if there are practical matters with this...
