Perhaps, but that's the definition of the difference between
"readable" and "searchable" (executable) directories.  In the example
of «foo/bar», if the parent of foo is searchable but foo is only
readable, then you can expand «*» to discover foo and attempt to
"read" under «foo/» for the existence of the known name bar, but you
can't "search" foo (expand «foo/*») to discover anything, so by
extension «*/*» can't include «foo/bar».
