Gemini does not equal Gemini
Not only the respective Ascendant but the other planets, houses and aspects of the respective celebrity birth chart make the difference. In short, there are a multitude of sign combinations making it nearly impossible for somebody to have the exact same birth disposition, unless of course, they are identical twins.
This is the reason why newspaper horoscopes for the Gemini can never be right, unless it's a dominant Gemini. For that to be true many aspects or planets pointing towards the 3rd house, the house of contact & communication, and/or many planets in Gemini must be a given. Since Mercury is the Gemini's ruler, its position plays a significant part in any Gemini' birth chart, too.
