Extent to me (L)eft, (B)ottom, (R)ight, (T)op  LBRT, from which you can derive the width, height, and the 4 corners. To me, when a map frame is rotated, you are rotating the axes (x, y) from their normal position (ie the old X-Y graph/axis).  Consider an "axis-aligned" rectangle, which means that the L,R are parallel to the Y axis and B,T are parallel to the X axis.  If you rotate the rectangle within  XY space then the extent must change because the position of the 4 corners of the rectangle change... try it. if the rotated rectangle's XY space is rotated by an equal amount to the above, then the extent returns to its original values (in terms of width and height... position of the corners is less relevant) So the 'extent' is the correct term for the 'normal' XY axis orientation and rotated XY frame.... the only thing that has changed is the orientation of the reference framt. When you mention layout, there was never any mention of layout's reference frame changing... maybe the map is rotated, but that rotation doesn't appear to the layout's frame space', so it assumes that it is getting a regular old XY 'graph' space and simply translates map coordinates into paper units.  So in my mind... if you rotate a map frame and don't "tell" the layout what you have done, it can only assume that the "extent" is derived in the same fashion. Sorry if I over-simplified things.  A classic example of application of this space reorientation deals with whether points are to the left or right of a line (eg point in polygon searches).  Instead of a whole bunch of stupid calculations to determine whether it is true or not, you simply rotate "everything" (points and the line) so that the line is either parallel to the X OR Y axis .... a series of calculations now becomes simple equality checks (ie <, =, > ) ...
