*grumble* stupid example. Complete Arcane errata even says that text trumps examples. And that means I don't even know what the RAW is for that new magical houseruled ability. Does that mean that the two features don't stack, or does it mean that the spellcasting advancement doesn't provide caster level advancement, or that caster level advancement only occurs every other level? For example, if I multiclass, can I apply the caster level advancement to one class, and the spellcasting advancement to the other, and end up with 15 total advanced caster levels (i.e. Fighter 2/wizard 2/Sorceror 2/GSA 10 with a CL of 12 for Sorceror, and 7 for wizard, with 7'th level wizard casting and second level sorceror casting), or arrrrgh brain explodes.
