I'm not sure if I understand the "without Net property" portion of your question, but if you're looking to reuse the 1st DDR components routing, use the steps below.
- Select the DDR component and it's connected traces/vias segments you want to keep.
- Make Reuse
- Right click and choose to Reset Origin, then select the datum of the DDR component
- Right click and save to file (with the reuse block still selected)
- Get the (x,y) of the 2nd DDR component
- Select it and choose the Make Like Reuse
- Use <ctrl-r> to rotate the reuse block
- Go to the Reuse properties and enter the (x,y) of the 2nd DDR component
- Break both reuse blocks
