Sort of found the answer. It is called a fasciated blossom. Seems like it is just a gene common in beefsteak tomatoes.
Fasciation in tomato flowers was described first in the 1920’s; a 1948 paper from the National Institutes of Health described the genetics of fasciated beefsteak tomatoes. In botany, fasciation is an event out of the ordinary, yet somewhat common.
