” So no matter his intention the pope is causing confusion.”
I’m not confused so apparently the problem is you.
Of course you aren't, I haven't heard of any protestant complaining about a Catholic pope seeking a public blessing from one of their own. They love it.
It seems that only a few traditional Catholics are upset by this stunt.
Again from the Council of Laodicea:
Canon 32
>>It is unlawful to receive the blessings of heretics, for they are rather follies than blessings. .<<
Once again, your problem is with the Catholic Church. Good luck in your catechesis!
