This kind of code is horrible as he admits, but I don't think it is
wrong; they just consider the RAM as being an external device, thus
using a holey boolean type.
When they compare their own booleans to True_State and False_State,
the result is likely to be stored in a register only and never in RAM,
and registers are probably considered as "safe".
