Simplified and Traditional are different (but closely related) writing systems that can be used to express the exact same text. They are not different linguistic variants of Chinese.
It looks like regardless of which writing system you choose, Google still translates into the most widely used variant of Chinese: Standard Chinese, as spoken on the mainland. It just writes the result using the requested characters. It doesn't decide to use more characteristically Taiwanese phrases if you select traditional characters.
In order to address the complaint here, Google could allow one to select the writing system (Simplified vs. Traditional) independently from the regional variety (Mainland, Taiwan, etc.).
