When working tomato blossoms, bees carry pollen from several different tomato plants they have visited on a single trip. So, the accidental crosses that occur can be from one or more pollen sources and not necessarily the closest source.
Moreover, the blossoms bees visit for pollen collection are those most ready to yield pollen in response to the vibrations emitting from the bees, who will skip over plants in their search pattern, not necessarily landing from adjacent plant to next closest adjacent plant.
I've watched carpenter bees work a couple of blossoms on one tomato vine, then skip ten feet or farther, ignoring several closer vines, and land on a vine quite some distance away.
As to what you may expect on a random cross with JBT, in the F1, if the unknown parent is round, you will get a round F1 fruit.
