This is correct. It's even documented in the release notes that
late-mounting /usr is not supported anymore.
https://www.debian.org/releases/stable/amd64/release-notes/ch-information.en.html#late-mounting-usr

You'll run into all sorts of problems and those will get worse over
time. Please either use initramfs-tools or don't use a separate /usr
partition.
I don't think we should make any changes in that regard and pretend we
still support this use case.
