I don't think so. For example, you have "Arial" font, picked by user.
You want to render CJK symbol. Fontconfig calculates that "Kochi Gothic"
font is closest to "Arial". Now you have "Arial; Kochi Gothic" font
list. If next required symbol is in either of them, then they are used
(in order); if not, say you want to render some math symbol, another
font lookup is performed and now you have three fonts in the list.

I haven't really checked it, but according to documentation, it should
work this way.
