Please have a look at the doc - https://commons.wikimedia.org/w/api.php?modules=query+categorymembers

Note: Due to miser mode, using this may result in fewer than cmlimit results returned before continuing; in extreme cases, zero results may be returned

The api module does not know that all the other pages will be just files and gets fitered out by the namespace condition. Therefor you have to continue over the empty results to know that.

You can avoid this by changing cmnamespace=14 to cmtype=subcat
