The first one works because *.* will match everything your current directory,
including sub-directories and it will recurse through each of them.  The
second example will first match anything in your current directory with a .log
extension and try to grep it (if it's a file) or recurse through it if
it's a directory.

What I believe you want to do (at least works on Linux) is
grep -nH -r "my pattern" --include "*.log" .
