There is a distinct difference between reversing capacity loss and reducing it. Reduction is very possibly a pro-active stance, where reversal is by nature passive.
In this case, what seems to be claimed is a pro-active method of reducing future loss of capacity. There is certainly a lot of precedent for this without my going into analogies. See the intelligent battery handling on the Tesla Model S. Sure there are many cells there, but I'm thinking there are more cells in this battery box than there is in your 6 or 9-cell laptop. Perhaps not, though. :-)
