It doesn't ask you about /home at all. It's a kinda hidden feature.

If you were doing manual partitioning over the top of an existing
linux install (i.e. a filesystem exists which contains /bin /etc /var
/usr /home and so on, and you choose not to format that filesystem,
and you choose to install on it, then it will recursively delete all
files in /bin /etc /var /usr and so on, but _not_ touch /home within
that filesystem.

I find myself explaining this to people about once a month. It's such
a hidden gem of a feature so many people don't know about it, but it's
the single most useful "upgrade without upgrading" feature.
