It appears to be so:

$ cygcheck -f /etc/defaults/etc/bash.bash_logout
base-files-4.3-2
$ ls /etc/**/*bash_logout
/etc/bash.bash_logout  /etc/defaults/etc/bash.bash_logout
$ zgrep bash_logout /etc/**/base-files*
/etc/preremove/base-files-manifest.lst:etc/bash.bash_logout
/etc/setup/base-files.lst.gz:etc/defaults/etc/bash.bash_logout

Whether it should be is a good question.

There's no /etc/bash_logout file under Debian, etc. but /etc/skel/.bash_logout 
and ~/.bash_logout also have the same clear screen code.

Is (or was) /etc/bash.bash_logout that did this in the bash sources or under 
Fedora, which is the Linux basis for some Cygwin approaches, behaviour, and 
conventions?
