Earlier quoted context omitted.
Perhaps there's a better way to characterize it? I'm talking about stuff like this for ASL: You look surprised => You look surprise They came here recently => Recent they come
You're asking about Subject-Object-Verb order.
It's not about the order of words but that grandparent seems to have misunderstood something about glosses. He is thinking that grammar is simplified. It is difficult for written glosses to express the complete grammar spectrum of Signed Languages.
It's unfortunate and similar to the Blub paradox: some people will unavoidably believe that Signed Languages have a simple grammar similar to Chinese when looking at glosses.
Additionally, my local Signed Language (Swiss German Sign Language) has quite a free order. Often topic-comment is applied. An example:
[Concerning the] weather, [I] think [it's] quite fine.
As glosses: WEATHER THINK GOOD.
The word «quite» is omitted because it's an inflection. In SGSL I would make a slightly kissing mouth, lower the eyelids somewhat and make very small and fast nodding movements.
That's not Subject-Object-Verb order.
Additionally there is a slight shift between WEATHER and THINK, it's difficult to explain, but perhaps a colon after WEATHER would help. WEATHER: THINK FINE. This what I called «shift» is an inflection: it puts the word WEATHER in topic mode.
Caveat emptor: I am not a linguist, but always have been very interested in linguistics and talk SGSL every day.
Edit: many little things.
