Does this help the roots uptake calcium & magnesium nitrate?
Ok, dammit lol..

That is true in concentrated solutions; on the ppm level calcium citrate is soluble (0.85g/l at 18C).I believe that the citric acid will combine with some (a small amount) of the Ca to form insoluble Calcium citrate thereby making less Ca available to the plant. (not that that's a big issue and in fact probably a good thing)

Yes, good point ... also citrate and malate together form a complex with Ca that is more soluble than either citrate or malate alone.
Citrate also helps to maintain phosphate availability when Ca and Mg are increased. This has been studied quite a bit for plants adapted to growing in calcareous soils many of which secrete citrate from their roots.
