Por que o mogrify gera mais arquivos do que o que eu forneci como entrada

Question

Eu converti alguns arquivos PDF em arquivos PNG usando:

mogrify -background white -alpha off -verbose -density 1000 -resize 1600 -format png ./*.pdf

no Microsoft Windows 10 (requer Imagemagick e Ghostscript para ser instalado).

Minha pasta contida antes de executar mogrify:
