This could be made more explicit: counter styles cascade "atomically". 
Unlike properties in normal style rules, counter descriptors do not 
cascade. For example:

@counter-style my-counter { type: repeating; symbols: a b; }
@counter-style my-counter { symbols: c d; }

The second rule completely masks the first one and is of type symbolic, 
the initial value. It does not merge descriptors with the previous rules 
as other types of rule do with properties:

@page { margin: 2cm }
@page { padding: 1cm }

Also, for the 'override' type:

If the specified counter style name isn't the name of any 
currently-defined counter style, it must be treated as if it was 
overriding the decimal counter style.

Does "currently-defined" means "before in cascade order"? Example:

/* 'bar' is not defined before */
@counter-style foo { type: override bar; }
@counter-style bar { type: repeating; symbols: "-"; }

Finally, does 'override' take the current algorithm at this point of the 
cascade, or the one that eventually wins?

@counter-style bar { type: repeating; symbols: "*"; }
@counter-style foo { type: override bar; } /*which is it?*/
@counter-style bar { type: repeating; symbols: "-"; }
