It's not quite the same stuff as glue. PVA glue is polyvinyl acetate, and PVA filament is polyvinyl alcohol. The glue doesn't dissolve in cold water like the filament does.
You are correct, should have double-checked that the two PVAs referred to the same thing.
I think the rest of my comment still pretty much stands though, PVA glue isn't quite water soluble but the cleanup for it isn't much more involved and doesn't involve any exotic solvents or anything
The paper the article is referencing says they made their own PVA glue from pellets so they could get the thickness they wanted, and they did so by dissolving them at 80°C, so it sounds like the glue is soluble, just only in hot water, and all the clothes I ruined as a child could have been saved by using a different setting on the washing machine.
