No, Toba catastrophe only talks about that breeding HSS population living 79000 years ago which direct contributed the most to the gene pool of the modern HSS population that lives on earth today. That particular population, call it A, dwindled down to a few thousand at the time of Toba eruption. Since that population's genes later passed onto to all living humans, all living humans carry in our genes the evidence of the Toba bottleneck.
Toba catastrophe says nothing about whether there were other populations of the HSS, HNS, or Homo Erectus on the earth at the time, or how they were effected by Toba. There could well have been many other populations of homo genus on earth at the time of Toba. Some of those population may have been wiped out by Toba, but some of those populations may well have not been effected much by Toba at all. We simply don't know. All we know is if there were a lot of other HSS populations 79000 years ago, they for whatever reason did not later interbreed extensively descendants of population A. They for whatever reason did not prosper genetically and did not contribute much to our gene pool.
