One planet guards two constellations, is the energy also divided?

In modern astrology, Mercury guards Virgo and Gemini at the same time. Venus protects Libra and Taurus at the same time In ancient astrology, Jupiter guarded Pisces and Sagittarius, Mars guarded Aries and Scorpio, and Saturn guarded Capricorn and Aquarius. Let's just talk about Mercury and Venus in modern astrology. The meaning of Mercury is simply to be in charge of communication, communication, consciousness, analysis and thinking of Venus, and simply to be in charge of pleasure, love, aesthetics, money and happiness. Therefore, Virgo, in general, we always feel that we are good at analysis, pay attention to conditioning and think carefully. Gemini, generally speaking, we always feel that we are good at communication, pay attention to communication and have an open mind. Taurus, generally speaking, we always feel that we are good at managing money, paying attention to material things and rest. Libra, on the whole, always gives people an impression of being good at enjoying, paying attention to beauty and loving seeds. So, a brief list, do you see the difference clearly? Although guarded by the same planet, they often show different things. And because Virgo and Taurus belong to earth signs, they are more restrained and practical, even in human design. Gemini and Libra are both air signs, so they always give people an unpredictable and erratic feeling. Finally, I come to the conclusion that Mercury gives Virgo energy for analysis and Gemini energy for communication. Venus, on the other hand, gave her financial management ability to Taurus and her energy to enjoy love to Libra.
