The relative precision with which these dances were conducted might lead to the proposition that they were somewhat mechanical in their execution. However, Schlemmer was not interested in pursuing such mechanical perfection for he considered that the human being should remain at the centre and as purpose of such work. 

我的翻译：这些舞蹈的相对精确性可能会导致这样一种说法：它们的表演有些机械化。然而，施莱默对追求这样的机械完美并不感兴趣，因为他认为人应该是这项工作的中心和目的。 

我的问题：第一句句末提到“表演有些机械化”，我理解这是一种贬义，指的是机械化不好，过于刻板。可是为什么在第二句中又用了mechanical perfection了呢？是不是应该理解为：“施莱默不关心是否机械化”呢？

谢谢老师！
