Maybe the following slightly different presentation may help

Scanner Colour Space
    transforme by inprofile for the scanner/camera to
    transformed by outprofile for the printer/monitor/whatever to
Output device space.

The first step is almost by definition to a larger colourspace as PCS,
either XYZ or CIElab, covers the full gamut of colours.
The second step almost certainly is into a smaller colourspace.
Here rendering intent indicates the preferred way of compressing all
possible colours into such smaller space.
