There's very little distinction there. Stalin made the same claims:
> An anecdote attributed to Molotov showed Stalin perusing a map of the Soviet Union saying: “Everything is all right to the north. Finland has offended us, so we moved the border to Leningrad. Baltic States ‑ that’s age-old Russian land! ‑ and they are ours again. All the Belorussians live together now, Ukrainians together, Moldovans together. It’s ok to the west.”

The territorial claims have continued unabated. This is why Russia was so peeved (and remains peeved) about NATO intervention in Bosnia; why Russia supports the breakaway Moldovan province of Transnistria; why it props up the Belarusian dictatorship, and has tried to do the same in Ukraine, ultimately resorting to a full-scale invasion.
There's continuity because there's alot of truth in Putin's claims regarding historical cultural affinity. The problem is, it's not the whole truth, and becomes less so every day, only accelerating since the breakup of the USSR.
