Sometimes the present participle can indicate that one action follows quickly after another. This prefers some kind of logical or cause-and-effect relationship between the two actions.
Notice the word connected in your grammar book:
we can use participle clause when two short, connected actions are close in time, even if they don't happen at exactly the same time.
My example:
Opening the envelope, I found five hundred dollars.
The relationship between the two actions is perhaps best expressed by
Upon opening the envelope, I found five hundred dollars.
or
I opened the envelope and found five hundred dollars.
It is not best expressed by
After I opened the envelope, I found five hundred dollars.
The above sentence does not express the same thing as the present participle. Because after does not require a logical or cause-and-effect relationship, and it does not require one action to happen immediately, almost simultaneously as the other. The sentence with after is better expressed by
Having opened the envelope, I found five hundred dollars.
Opening the file, John called David.
If you, as the writer, feel that there is a "connection" (relationship between these two actions, logical or cause-and-effect or something else), then the present participle is fine. Only you as the writer knows if such a connection exists.
The same goes for
John, opening the file, called David.
The OP's question is: Do they mean the same thing. The answer is yes.
The more common way to phrase it (assuming the two actions were happening at the same time) would be:
While opening the file, John called David.
