What it says about post-1970-01-01 00:00:00 UTC times is:
Time in Northern Vietnam
January 1, 1968 - June 12, 1975 UTC + 07:00:00 Hanoi time zone
Time in South Vietnam
January 1, 1960 - June 12, 1975 UTC + 8:00 pm Saigon Standard Time
The time in Vietnam is unified
June 13, 1975 -nay UTC + 07:00:00 Standard time zone
with no indication about standard vs. summer time; the tzdb doesn't show Vietnam ever having seasonal time shifts, so that makes sense. The only reference given on the page doesn't seem to, in the generated translation, address time zones at all.
And, no, it says nothing about Thailand, but, as noted, North Vietnam happened to keep the same time as Thailand from 1970 to reunification; *that's*, plus Bangkok being larger than Hanoi, why Asia/Bangkok is used as the tzdb id for that region.
