MATCHPROP transfers properties from a source object onto others, so the CAD crosshair gives way to a monochrome paintbrush whose tip sits on the pick point - the AutoCAD feel for the same command. The glyph borrows the crosshair's own colour (including a user-customised one) and uses a single stroke weight plus one filled wedge, so it reads as part of the CAD cursor family rather than clip-art. It is drawn instead of the crosshair, never on top of it, and only while the command is armed.
