As I think has been said before, technically not.
This is because the new instruction cancels the restriction of the previous instruction, unless the restriction is included in the new clearence.
i.e. "Descend FL100 to cross SABER FL150 or below".
However this tends to clutter the R/T especially when Lambourne is bandboxed with NE Deps, and anyway the descent profile tends to make sure that the SABER restriction is met.
Clear as mud I know!!!!
