LinuxCNC and G Code ripper

I am trying to set the bed level using g code ripper based on nice video on g code ripper .
What I do not understand is how linuxcnc (in that video Mach3 was used) corrects itself from the probed data.
After setting the probe at the touch point with the offset, the probe scans at different points. Does this point is stored and linuxcnc corrects itself automatically when it hits at that point?

Or is that video missing some intermediate steps before linuxcnc actually starts the machining?

I am using this swicth for the bed leveling and any inputs is appreciated.

I found the document to answer my question. The command G38.x is used to probe and after successful probing, parameters 5061 to 5069 will be set to the coordinates of X, Y, Z, A, B, C, U, V, W of the location of the controlled point at the time the probe changed state.
