What is the difference between "satisfactory" and "satisfying"? Sometimes satisfactory things are not satisfying. What do they mean? Do they both mean the same thing?
Both words are similar in meaning, but each one has a slightly different focus. Satisfactory keeps its focus on the object that it describes. But satisfying shifts the focus a bit -- it focuses on how that object relates to others.
"This burger is satisfactory." (Sounds like something a judge would say at a grilling contest.)
"This burger is satisfying." (Sounds like what a restaurant patron would say.)
The contest judge says it's satisfactory, because it checks all the boxes on his sheet. The patron tells the waitress that it's satisfying, because the waitress is tending to his experience.
So satisfactory describes something in relation to an objective standard, but satisfying gives a subjective description of the thing. One has a more formal and impersonal tone, the other has a more informal and personal tone.
Satisfactory means something is enough or accepted. On the other hand, satisfying is something that is up to the mark you need or expect!
Said that, if someone's performance is satisfactory, it means the performance is acceptable. If it is satisfying, it touches the standards you expected!
In the sentence in question, the author means to say that in some cases what seems satisfactory (acceptable) is not even satisfying (what you expect).
The difference between these is the same as the difference between the verb "to satisfy" and the noun "satisfaction".
Satisfy (v): Meet the expectations, needs, or desires of (someone)
Satisfaction (n): Fulfillment of one's wishes, expectations, or needs, or the pleasure derived from this
To say something is satisfactory means it satisfies a particular condition.
