No, no, no, and a thousand times no!  Changing the framelines doesn't
"change the metering":  it merely reflects a zone in the VF of what area the
meter is reading.  The metering stays the same -- it reads an area on the
front shutter curtain.  When you change the lens from one focal length to
another, you change the effective are OF THE IMAGE which is metered -- but
you don't affect the area of the curtain which is being measured.

Maybe some other LUG can describe this better than can I.
