My assumption is that you are seeing two different results. One is for country specific and another is for .com.
For me, from Chrome address bar, it takes me to the country specific results. If I go to www.google.com then obviously it's going to be a different results.
For me, both go to my country-specific domain (google.com.au), yet I get different result sets.
