Everything fits into individualized scenarios with many different variables and moving pieces. It's something I've tried to stress heavily on this forum on many issues because as a society we look at these things as very black and white and view things as being tight protocols. Any time I suggest things can enter decision-making that's influenced by a myriad of other issues not pertinent to the actual issue at hand, people act like I'm crazy, because from a societal point of view everything always looks all neat and tidy and all science-y where they ask the magic 8 ball and the universe spits back unadulterated truths.
That said, I have no idea what's going on here, but a disagreement in how this is managed, even amongst competent professionals, is not out of the ordinary, and I'd even argue is standard. People are going to have strong opinions. I've preached Venn-diagram influences in these decisions and absolutely nobody makes a decision they otherwise didn't have the ability to make simply by something like spite or bias. It's just that the bubble for spite and bias moves around and influences the decision to be made that's more consistent with it. This can be a very unconscious process.
I don't know if what factors into this or why said decision was actually made, but the above is completely reasonable. Never assume that there's one well laid out pathway that you follow that comes from some holy writ of medical practice. There's more uncertainly and guesswork and bias at the highest levels than anyone cares to recognize.
