An empahsis or anything else?

I came across a phrase "removed and gotten rid of" in the paragraphs cited in the below. "To remove" and "to get rid of" are similar in meaning to each other. Are they just used for emphasizing the activity of removal or saying something emphatic about the manner of removing? If they are not, what can be the reason for using these words similar in meaning?

One tactic to help bee populations stay healthy is “hygienic behavior,” or the ability to identify and remove diseased bees from the colony. Brenda Kiessling says the beekeepers test for this by using liquid nitrogen.

"We freeze 100 cells. We come back in 24 hours and we test what percentage of the cells the workers have removed and gotten rid of. Queens which have a hygienic percentage of 95 or 100 percentage are excellent."

The above paragraphs are taken from Voice of America's website and they are transcripted from the voice of the video recording, which can also be seen on the same page. The video recording is about bees nowadays in the U.S.

Thank you for your attention!
