I don't see how. The builds come from different places using a combination of a couple CI engines and local builds. (This ignores the PPA)
The maintainers are in different time zones and the build processes take different times and effort to "trigger"
For 0.19.1 we created the tag without a release and this caused confusion. In addition there were concerns that we held up the release for the Win binaries.
For 0.19.2 we created the tag and release at the same time, there were/are concerns that we didn't hold up the release for the Linux/OSX binaries.
