That's correct: the one piece of information that is stored
separately from the config.pl file is that path to the config
file itself.  That's how BackupPC finds the config file.  As
you discovered, it is stored in lib/BackupPC/Lib.pm.

It's correct.  $confDir is a function argument.

That's right: you have now correctly pointed your second installation
at the second config.pl file.

With FHS (the default in 3.0.0) you need to use the --config-dir
option to configure.pl to explicitly place the config dir on the
second installation in a new place.  You manually made the right
change.
