But doesn't the Adobe color engine work in Lab anyway?

internally, but that's not the same as making a conversion of the image twice.

What are the two conversions?

nospam
rgb->lab->rgb

But isn't that exactly what the colour engine has to do?

It gets fed an RGB file from outside, then converts it to Lab for it's own processing and then converts it back to RGB for output to the monitor. It may also convert it to CMYK for output to a printer or saving it to a disc. http://www.eizo.com/global/library/management/cms/02e.jpg is the kind of diagram commonly used to explain this. --
