[Grammar] must be needing me

[mihallure]

I've recently watched the film "Saving Mr. Banks" and I was a little intrigued by the use of the verb "to need" in the continuous aspect in the sentence below:
"I had the impression a certain friend might be needing me".
Is it used correctly?
Thank you!

Yes, it is.

Yes, it is.

Thank you!
Is this structure really common or is it better to use it in the simple aspect?

The continuous could suggest the limited duration of the need of its immediacy - now..
