Indeed.  The "cursor" in that node means that rectangular block which
marks where point is; Emacs moves it to the coordinates that best fit
the location of point when point moves or the buffer displayed in a
window changes.  "The cursor jumps" wants to say that Emacs draws the
cursor at those coordinates (or thereabouts).

In this sense, the "cursor" part of cursor-sensor-functions is a
misnomer; it should have used "point".  However, given that this was a
replacement for point-entered and point-left properties, I can
understand why that name was chosen.
