deploy snapshot without timestamp

I've created maven project in which I want to deploy snapshot version to snapshot repository without timestamp.
So, in tag snapshotRepository I've declared snapshot repo like this:

<distributionManagement>
	<!-- ... -->
	<snapshotRepository>
		<id>repo-snapshots</id>
		<name>Snapshots maven repository</name>
		<url>[repo snapshot url]</url>
		<uniqueVersion>false</uniqueVersion>
	</snapshotRepository>
	<!-- ... -->
</distributionManagement>

What is important, I've added <uniqueVersion>false</uniqueVersion> to force deploy process to not add tiestamp. But after invoking goal

mvn deploy

In repo is uploded snapshot with timestamp instead of SNAPSHOT postfix

Full prepared pom.xml for testing is in attachment for this issue.
