I think he means them not renaming the band for the new tour, seeing that Neil passed away and all. Neil's widow and daughter are onboard with it though:

"Carrie Nuttall-Peart and Olivia Peart, Neil’s widow and daughter share:

“We are thrilled to support the Fifty Something tour, celebrating a band whose music has resonated and inspired fans for generations, and to honor Neil’s extraordinary legacy as both a drummer and lyricist.

Neil’s musicianship was singular. Compositions of intricacy and power that expanded what rhythm itself could express. As both drummer and lyricist, he was irreplaceable. Inimitable in his artistry, and unmatched in the depth and imagination he brought to the lyrics that inspired and moved so many, he profoundly shaped how fans connected with him and the band, giving voice and meaning to their own lives.

As the band enters this new chapter, it promises to be truly unforgettable. We are excited to see how their new vision unfolds, and to hear this legendary music played live once again.”"
