For me this is typeset using LM Type1 fonts, not the OpenType LM math
font which explains why both are correct, after adding
\setupbodyfont[modern] the first * is raised than the other but still
readable.

It seems that * in math mode should map to U+2217 (which is what \ast
maps to) and not the ASCII asterisk.
