The people who thought the referendum was illegal and didn't matter, didn't show up. In part because of fears of violence from police (shall we say) "enthusiastically" enforcing the law. The people who wanted the referendum to go through were motivated to show up despite the violence. Because they believed in their cause. So no, the "yes" voters were likely not discouraged from showing up. Or, the "soft" yes votes were discouraged.
