This step name doesn't match your others. Maybe 'copy repo from Android'.

repo re-sync followed immediately by repo sync is a little confusing.

good spot! I actually reshuffled the steps so that I could remove the 'sync -l'

This step only exists of chromium_org does, so doesn't need 'potentially stale'
in the title? Sorry for the nits on step names, I'm just too aware of the
limitations of the buildbot waterfall display and these long names will end up
wrapped, ugly, and unfortunate :(
