hexagon example does not work as expected

An example taken from https://usage.imagemagick.org/canvas/

magick -size 24x24 xc: -draw "rectangle 3,11 20,12" tile_line.gif
magick tile_line.gif -gravity center \( +clone -rotate 0 -crop 24x18+0+0 -write mpr:r1 +delete \) \( +clone -rotate 120 -crop 24x18+0+0 -write mpr:r2 +delete \) -rotate -120 -crop 24x18+0+0 -write mpr:r3 +repage -extent 72x36 -page +0+0 mpr:r3 -page +24+0 mpr:r1 -page +48+0 mpr:r2 -page -12+18 mpr:r1 -page +12+18 mpr:r2 -page +36+18 mpr:r3 -page +60+18 mpr:r1 -flatten tile_hex_lines.jpg
magick -size 120x120 tile:tile_hex_lines.jpg tiled_hex_lines.jpg

produces:

Tested with 7.1.1-43.

Using magick convert instead of magick produces a bit better result:

In IM 7, the use of -page needs to be enclosed in parentheses

magick -size 24x24 xc: -draw "rectangle 3,11 20,12"  tile_line.gif

magick tile_line.gif   -gravity center \
          \( +clone -rotate    0 -crop 24x18+0+0  -write mpr:r1 +delete \) \
          \( +clone -rotate  120 -crop 24x18+0+0  -write mpr:r2 +delete \) \
                    -rotate -120 -crop 24x18+0+0  -write mpr:r3 +repage \
