See, this is exactly what RICE RACING is complaining about. The idiots have now confused you by using incorrect, made-up terminology. I would like to point out that the latest iteration of this ignorance made its way from this forum to rx7club.com, so it does work both ways.

When one compressor feeds into another it is called "staging". The setup is usually described in numbers of stages. For example, one compressor feeding into another is called "2-stage", 7 inline compressors are called "7-stage", and so on. Therefore, if you had an engine with one compressor feeding into another, you would describe your setup as a "2-stage turbocharged engine" and you would describe the method as "2-stage turbocharging", or more generically as "staged turbocharging" or simply "staging".

Garrett TPE331 engine shows the design differences between the high and low compressor stages (painted blue in the cut-away picture). The resulting compression ratio was 8:1.

Where is The Lounge? I haven't seen it in about a year now, so I figured it was deleted.
