It is true, because the devs have been quoted numinous times as saying so at one time or another, only to back track later.
Honestly, I feel openSUSE Dev lacks vision and likely does not know what they're doing anymore. They'll announce something today, only for tomorrow to claim that has changed, only the day after to claim it is all back on track.
They flip-flop continuously. From claiming Leap was going to be discontinued, to claiming Leap was still going forward, then discontinued, then immutable, then discontinued, then continued as normal. They've changed their minds so many times, I'm sure I'm missing one!
