I won’t memorize it either, but I bookmarked the message.

The sed / xargs part was "for fun." Because regexes are fun, right?
To answer your other question, yes; the port echo line will only show
installed ports that have (but may or may not be selected) both a quartz
and an x11 variant.
For reference, here is the command again;
port echo active and variant:quartz and variant:x11 \
| sed -n -e '/\+quartz/d;s/@[^+-]*//;s/\+x11/-x11+quartz/p' \
| sudo xargs -n 2 port install
Breaking down the sed/xargs portion, it:
1) Checks for +quartz to be present (and thus currently active) and ignores
('/d' for delete and continue) those lines. I do this because some ports
(notably cairo) can be both +x11 and +quartz.
2) Removes the version information (between the @ and the first + or -;
will fail as noted if the version string has a + or -)
3) Searches for lines with +x11, and replaces that with -x11+quartz (the
desired action originally requested) and then (/p) prints only those (-n
argument) lines.
xargs -n 2 then takes each set of two arguments (<port> <new variants>) and
calls "port install" with those arguments.
Glad you found it useful; perhaps you'll find it fun. ;)
