Young Stribling - a heavyweight champion?

There are few versions of events that transpired after Max Schmeling defeated Jack Sharkey by DQ in June 1930 to become the new heavyweight champion of the world. In the most popular one, Schmeling was stripped by NYSAC for not giving Sharkey the rematch, defended his NBA title against Young Stribling in July 131 and then lost the rematch with Sharkey for undisputed recognition in June 1932.

However, I read some accounts that Schmeling was also stripped by NBA, who started to recognize Young Stribling as their champion after defeating Tuffy Griffiths in December 1930 and Schmeling took this title from him in July 1931. BoxRec quotes the following United Press article about Stribling vs Griffiths:

"The addition of Young Stribling to the ranks of recognized world heavyweight title claimants complicated today the championship muddle which has existed since Gene Tunney discarded the crown two years ago. Stribling's claim to the title was based on an unpopular 10-round decision over Tuffy Griffiths at Chicago Stadium last night. The bout was recognized by the NBA as a championship contest. Like Max Schmeling, Stribling proved to be disappointing in winning his claim. Stribling allowed Griffiths to set the pace for eight rounds and only in the final two stanzas displayed anything like championship ability. Stribling's late rally caught the judge's eyes and won the decision."

So, was Young Stribling retconned from being a champion like Peter Maher was? Did anyone research this particular matter?
