Nope I don't understand that at all. When Bruce did the interview and things where said about saying goodbye to Bruce, his last interview as Bruce, meeting her, living a lie...I don't think he's saying he's the same person at all.
You can't have it both ways. He can't say his had to hide who he really is and did things to run from how he really felt because that was what was expected of him and say he's still going to be the same person and his children don't have the right to feel hurt or lied to.
I find it interesting that you think being transgender is as simple as preferring to wear a dress and have boobs.
You can't say I'm now a woman but I'm still your dad. That person who was "dad" was not the real you, it was an act. If you are a woman, you are not a dad.
