All european countries were already on the same trajectory. Russia was lagging behind for perfectly understandable reasons, but it was on the same trajectory. The soviet movement came at the right moment to benefit from this (and yeah, there’s a good chance they accelerated it, and in the worst case were “not bad” as someone phrased it).
A government would have had to monumentally screw up to not benefit from the rapid changes across europe at the time.
If the OP (or many of the commenters here) want to demonstrate uniquely soviet achievements, there are better metrics to focus on than life expectancy.
The graph serves as simple contextualisation.
