Yes. Looking at the PostScript file, you see actual postscript commands
in the eps file, but the converted ps file has a raster image embedded.
Also the latter file is orders of magnitude larger than the former.

I think ImageMagick is a doing a direct translation from PS commands to
PDF commands... and so the commands are being preserved rather than
being converted. Why it happens that way, I don't know.
