As far as I can tell, it means essentially nothing. All SPI is by definition, "multi layer" since it tracks at least both layer 3 and layer 4. It looks like a term added to SPI to make it sound like its looking at more "layers". It's probably a term cooked up by the marketing departments of SPI firewall vendors.
You see things like this a lot, especially in the security product arena. Companies invent terms to make their technology sound new or unique when they are neither.
