I can confirm this, because librechroot runs arch-nspawn with the -f
$interpreter flag which copies the file inside the chroot

/bin/librechroot:73:    local setarch interpreter
/bin/librechroot:75:            armv7h) setarch=armv7l;
interpreter=/usr/bin/qemu-arm-static    ;;
/bin/librechroot:76:            *)      setarch=$CARCH;
interpreter=/usr/bin/qemu-$CARCH-static ;;
/bin/librechroot:83:                         -e "interpreter $interpreter" \
/bin/librechroot:88:                    plain 'This requires a
binfmt_misc entry for %s.' "$interpreter"
/bin/librechroot:97:            arch_nspawn_flags+=(-f "$interpreter" -s)
Usage: arch-nspawn [options] working-dir [systemd-nspawn arguments]
A wrapper around systemd-nspawn.  Provides support for pacman.

    -C <file>     Location of a pacman config file
    -M <file>     Location of a makepkg config file
    -c <dir>      Set pacman cache
    -f <file>     Copy file from the host to the chroot
    -s            Do not run setarch
    -h            This message
