You got it wrong: saving a jpeg in ANY quality (higher or lower) causes loss
of quality. Saving in the same quality as the original image causes quality
loss depending on the selected quality.
As I said, the only effect is a similar(!) file size, and that every save
would cause about the same amount of quality loss.
Jpeg is lossy, in whatever quality you save your files. If you save your
file in 75% percent, load it again, and cycle you will loose quality
_every_ time you save, not just the first time.
