Hi,

Below is the power connection of the DDR3 that is presented on the T1024RDB schematic. I couldn't understand why such a connection (highlighted portion) is made.

This figure is from T1040QDS schematics where they explains that connection. For the T1024RDB schematics it should sounds like “Decoupling between 1V35_SLP and 1V35 power split located under DIMM. Place these caps around DDR Power Pin areas to stitch return current flow for Address and command signals.”
