Glue joints can certainly be starved when using PVA and other glues. And this is using woodworking clamps. I have done it, not for a lack of glue mind you, but for an excess of pressure. I would noe subscribe to the technique described for the application specified. Nor would I use PVA. Plastic resin glue. Look it up. Precatalyzed and then powdered is plenty fine. PVA is a lazy man's glue and for a good reason - it is effective in many applications. In your application you can do a lot better than PVA for not much if any more money.
I have glued many species of exotics. Not once have I "removed oils" with acetone or whatever. Not once has a joint failed. Cocobolo, Brazilian rosewood, purpleheart, teak, whatever.
With experience you will know when a joint is clamped up properly. If you are exerting might beyond one handed tightening you are trying too hard.
