identifying the most constant stars in the field, (b) computing an artificial
comparison star by taking the weighted mean of the instrumental magnitudes of
these constant stars, using weights inversely proportional to their standard
deviations and, lastly, (c) comparing the instrumental magnitude of our star to
that of the comparison star. In this last step we subtract the magnitude of the
star from that of the comparison star: in this manner, positive values mean
that the former is brighter than the latter.

deviations and (c) subtracting the magnitude of the artificial comparison star
from that of our star. This, along with the fact that magnitudes become lower
the brighter astronomical objects appear, implies that:

(1) Negative values in the light curve mean mean that our star is brighter
than the artificial comparison star, and
(2) A decreasing differental magnitude in the light curve means that our
star appears brighter.

I would put it the other way around because is usually what happens in reality (e.g. transit):
An increasing differential magnitude in the light curve means that our star becomes fainter.
