The 1970 Swedish Open was a combined men's and women's tennis tournament played on outdoor clay courts held in Båstad, Sweden and was part of the Grand Prix circuit of the 1970 Tour. It was the 23rd edition of the tournament and was held from 2 July through 12 July 1970. Dick Crealy and Peaches Bartkowicz won the singles titles.
Either Dick Crealy or Peaches Bartkowski won the Swedish Open in a year other than 1970.
It is not correct or incorrect in context because there is no way one could know, yet it could be true. It may have fooled the system because my sentence contained things in the statement; for instance, I didn't say 1971 (which would have stood out), I said "other than 1970" (meaning not 1970).
