Yes little if anything had been done to the two SWIFT Centre buildings since March.
The "missed" point would be that the Nano Factory building site lies between the South tower and the blue metal buildings that lie east of Tech City. These blue building can be seen through the south tower structure.
If significant above ground work on the Nano Factory had begun (erecting structural steel, standing up one or two story pre-fab panels), then that would probably be visible. I see nothing of that nature.
The green bridge is just east of the IIITG Boys Hostel.
