Almost, but not quite.

Find pattern, cuts it out, s// finds nothing so prints remainder of pattern buffer. So it acts like the p
The let's call it "empty regex" uses the last one applied right before. In this case: reuse the address one to find the line. (Not easy to find in the docu. I didn't. I learned it from these fora.) Nothing is printed here.
Quote:
First pass N loads next line into pattern space, no match, unloads pattern space with p, blank line.
Goes back then finds pattern, which is deleted with // and then prints remainder with p
Nothing is deleted.
N just collects line after line into pattern space. The
p flag to
sed's
s(ubstitute) prints only if a substituition was made, i.e. when the pattern was found. Then also ignore the
T command and leave.

SYNOPSIS
fc-match [ -svV? ] [ --sort ] [ --verbose ] [ --version ] [ --help ] [ font-pattern ]

--sort is given, the sorted list of best matching fonts is displayed. With --verbose, the whole font pattern for each match is printed,
otherwise only the file, family and style are printed..
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
-v --verbose
Print whole font pattern for each match.
-? --help
Show summary of options.
-V --version
Show version of the program and exit.
-s --sort
Displays sorted list of best matching fonts.
