A comparison between gerunds and infinitives

Hi:

Below are the explanations that the englishpage.com gives, as follows, and I have some question:

Original explanation:

Although the difference in meaning is small with these particular verbs, and gerunds and infinitives can often be used interchangeably, there is still a meaning difference. Using a gerund suggests that you are referring to real activities or experiences. Using an infinitive suggests that you are talking about potential or possible activities or experiences. Because of this small difference in meaning, gerunds and infinitives cannot always be used interchangeably, such as in the examples below.

Examples:

• The British reporter likes living in New York. He lives in New York and he likes what he experiences there.
  
• The British reporter likes to live in New York whenever he works in the United States. He likes the option or possibility of living in New York when he works in the United States.
  
• I like speaking French because it's such a beautiful language. I like the experience of speaking French, and the way it makes me feel when I speak the language.
  
• I like to speak French when I'm in France. I prefer the option of speaking French when I am in France.




My question is for "likes to live in New York whenever he works in the United States", Now that he likes the option or possibilty of living in New York when he works in the US, Where is he living now, in New York or other places. Along these lines, the second pattern, I like to speak French when I'm in France. Can he speak French. What does it mean?



Thanks very much!
