The point of collecting click data is not to target google engineers, it is to collect data from masses of people doing regular searches and to improve them by seeing which links get clicked on, so obviously Bing is "taking data for non-google engineers". Furthermore, there's no indication that google search results pages are even distinguished from other pages in this.

In fact, the data that it takes from Google engineers for carefully engineered corner-case searches is the exception.
