But in that case the sucker has immediately become a raceme. I concluded that I couldn't actually see a sucker in the photo at all.
@tipson4490, the reason there are so many theories out there is because there are so many gardeners...each one has his/her own way of doing it. In moist or humid climates, air circulation is important for tomatoes, which can be susceptible to assorted mildews and fungal diseases. If you are in an arid climate, thicker growth works fine. You choose your method based on your space limitations, support structures, water availability, pots vs in-ground, and aesthetics. With the indeterminates, not pinching out the suckers, especially at the top, often results in a huge, sprawling mass which can become top-heavy and unmanageable unless you have a large support system. Some people just let them sprawl and are fine with that. Your choice.
