Had to go check the actual language in the source article to make sure this is what they wrote:

For SLS, two well documented, and visible changes have been made to the boosters, which are technically called Five Segment Reusable Solid Rocket Motor (RSRMV): the addition of a fifth propellant segment and the removal of all recovery and reuse hardware.

That's in the source article's third paragraph.

I hope "NasaSpaceFlight.com" isn't connected with the actual NASA by anything other than name.

Noticed that, too. College educated writer, no doubt.
