It certainly seems that way.
The over-riding concern of leave voters was to reduce immigration to the UK.

No, it wasn't an over-riding concern. It was the concern mentioned by a plurality of voters prior to the referendum.
You know what else was just as important? British economy. Plus ability to travel freely to the EU, ability to trade with members of the EU, impact on services and impact on jobs.
All of those combined override immigration by approximately 2:1.
