Exactly. Young's Adam-God teaching was immediately controversial. Young had ample opportunity to explain any sort of misunderstandings that may have existed, but there does not seem to be any record of him doing so.
Here are some pertinent observations recorded by Wilford Woodruff:
"President Young followed & made many good remarks . . . He said that our God was Father Adam. He was the Father of the Savior Jesus Christ--Our God was no more or less than Adam, Michael the Archangel." February 19, 1854
"Brother [Orson] Pratt ... could not believe that Adam was our God or the Father of Jesus Christ. President Young said that He was ... [He] brought Eve with him, partook of the fruits of the Earth, begat children and they were earthly ... [Young] told Brother Pratt to lay aside his Philosophical reasoning and get revelation from God to govern him and enlighten his mind ..." September 17, 1954
If Young intended to teach somehing like Adam Sr./Adam Jr., he could have simply explained it to Pratt. Instead, Young essentially told him to stop trying to make sense out of it and just accept it as revealed truth.
"... the doctrine of the plurality of God and that Adam is our Father is a true doctrine revealed from God to Joseph and Brigham." September 4, 1860
Some thirteen years later, Young continued to teach Adam-God without making any sort of Sr./Jr. distinction:
"At meeting of school of the prophets, President Young said Adam was Michael the Archangel and he was the father of Jesus Christ and was our God, and Joseph taught this principle." December 16, 1867
As others have noted, the Adam Sr./Adam Jr. hypothesis is ad hoc and out of harmony with the available evidence.
