$ dak ls chromium
chromium   | 73.0.3683.75-1 | green      | source, amd64, arm64
chromium   | 73.0.3683.75-1 | landing    | source, amd64, arm64
chromium   | 73.0.3683.75-1 | purple     | source, amd64, arm64

So, according to our archive (*the* authoritative source for questions
of which package version is where) this is fixed in PureOS, and for
about 1-2 days already.
It is a bit odd that apt-policy doesn't seem to reflect that - did you
run an apt update before? Maybe there was some other kind of lag
somewhere? (actually hard to tell now)
>From a new debspawn chroot:
root at sirius-green-amd64-yzj3:/srv# apt-cache policy chromium
chromium:
  Installed: (none)
  Candidate: 73.0.3683.75-1
  Version table:
     73.0.3683.75-1 500
        500 https://repo.pureos.net/pureos green/main amd64 Packages

Cheers,
    Matthias
