Technically, Tycho build generates two qualifiers, one for
Eclipse/OSGi/P2 metadata and one for Maven. Although I believe Maven
qualifier is not important for the Eclipse Platform build, I still
wanted to mention it... in the interest of full disclosure, so to speak ;-)

What is the usecase for using different version qualifiers for different
projects from the same git repository?
