They really had no choice but to change their advice. Surely it should read ‘there is no or little evidence that it is reversible’.
This seems to be open to interpretation. It does seem like a court case waiting to happen.
NHS website says
Little is known about the long-term side effects of hormone or puberty blockers in children with gender dysphoria.
Although the Gender Identity Development Service (GIDS) advises this is a physically reversible treatment if stopped, it is not known what the psychological effects may be.
Then it lists other side effects. What I found interesting is that NHS is laying the responsibility wholly on GIDS service with the "GIDS advises" sentence. Does that mean the GIDS service is outsourced to Tavistock? Earlier today I had a look to see what the GIDS service was saying about puberty blockers but I couldn't get to grips with the website and had to give up.
