I hope this information clarifies why you can, at times, see different IPs in different services. If the majority of your queries are coming from your real location and if all of a sudden you change your location (by using a VPN), Google's Artificial Intelligence will provide a result based on the average of your activity.

Google's Artificial Intelligence will provide search results based on the analytics of all of your services. However, Google will not be taking information only from your search activity, it will be tracking your information from all of your Google services, for instance, Gmail, Google Maps, Google Drive, etc. It will learn about your searches every time you use Google to look for something. The Google search engine implements Machine Learning and Artificial Intelligence to provide a better experience. How does that happen? We need to take into consideration how Google services work. While Betternet hides your current location by assigning another IP, sometimes searching on Google could get you results from your real location.
