PAVO Refschool practice tests

[pavbref]

I am using ref school on the PAVO site to practice for the NCAA rules test. What is the proper answer for the following question:

An errant ball rolls onto the court during a rally, and the referees stop play and signal a replay. The Team S captain immediately asks for a lineup check before the first referee authorizes the next serve. The second referee should allow the lineup check even though the rally was not completed.

Per rule 11.1.1.1, a completed rally must occur between interruption requests. A coach cannot ask for a lineup check in the situation above. Why can the floor captain ask and b granted the line-up check?
