No, we are describing the same thing. Sensor reads first curtain and

camera holds back the second curtain until sufficient exposure is
achieved.
If the brightness level is high enough, this point is achieved before
very
much film is exposed by the first curtain. If the brightness level is
low,
more and more film is exposed to the sensor before the second curtain
is
released. So, the OTF metering uses the curtain as an augment to get
things
moving, but dynamically moves into more and more film as the exposure
is
extended.
Thanks for that great summary.
