I suspect that it doesn't. Older sets w/o a product detector the bfo would cause the S meter to read the signal level of bfo rather than the level of the incoming signal.
Some sets when the bfo is turned on the S meter is turned off.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
