No, from the \set statements.  They are setting countPercentRepeats and
repeatCountVisibility in the Bottom context while the engraver actually
looking at them is in Staff context and consequently queries the
properties at Staff level which are unfazed by changes at Bottom.

So you need to write

   \set Staff.countPercentRepeats = ...

and similar.
