Well, Stalin did say "Soviet People", not "Soviet Peoples". The concept of Soviet People was also prominent post-Stalin.
Basically, everything can be a nation!
"Soviet peoples" and "Soviet people" were used interchangeably under Lenin and Stalin to refer to the former, meaning nations grouped under the banner of the USSR. After them, however, the Soviet revisionists had this idea of a "unified Soviet people" as a way to encourage the Russianization of the other cultures, and even talked of a "universal socialist nationality" in regards to the USSR and the Warsaw Treaty states.
