Why is "complete actions"?
"When we use it in this way"=> which/what way?

Try looking at the future continuous in terms of the present continuous.
What that Cambridge grammar means:
The government is making a statement today.
COMPARE:
The government will be making a statement tomorrow.
It's complete actions, not completed actions.
COMPARE:
The author chose to call that a complete action. Something definite in the future. Probably not the best choice of word. However, the use shows a higher level of activity. Rather than the more dull: The government will make a statement later.
"When we use it [future continuous] in this way, will be (doing) is similar to will (do) and going to (do)." going to do is more definite as a usual future form. "will" is just will. Often, intention to do something in the future.
it= will be doing.
will be [action verb] is just that. In the future, there will be an action that is describing something that in the present would be present continuous.
Conversation:
Mark: Hey John, so what will you be doing during the summer holidays?
John: Oh man, I'll be surfing for sure.
Why does Mark use the future continuous?
Mark: Hey John, what will you do this summer?
John: Oh man, I'll be surfing.
I'll be surfing is much more active (more physical) than: I will surf.
COMPARE:
Mark: Hey John, what will you do when they find out you stole the surfboard?
John: I won't do anything. After all, it was really mine.
There will means intend in the future. What do you intend to do about it?
Mark: Hey John, what are you going to do this summer?
John: I'm not going to do anything. Just sit around and relax.
That last one is just a straightforward future.
Note the word "also." I'm not sure whether the context was "We use [some other forms] to talk about complete actions in the future," like maybe simple future tense, or "We use future continuous [for other situations]," like maybe for future actions that will be ongoing for indeterminate amounts of time. Like "I will be attending Cambridge next year."
Either way, the point is: We also use other forms for this purpose, and we also use this form for other purposes. But to explain this particular usage, future continuous can be used for things in the future that will start and finish at a definite time, just as we use simple future, not just for things that will be ongoing or that are unclear about their time span.
But I would echo FumbleFingers advice: I would see this page as explaining a usage that you might encounter, not advising you that you need to use the continuous this way. It's not wrong to do so, but it's confusing, and there's nothing wrong with sticking to simple future for now.
