I heard a quote of Osensei that he is supposed to have said "Enter through form, exit from form." So perhaps the change was a move away from pre-war strict form?...
I believe O Sensei quoted this from one of the principles of the concept of Shu-Ha-Ri - "First learn the primary tools then use the tools to create new (or secondary) tools" - or something along this line. There is no permanent change, the change is part of a cycle. As a student on a learning path, changes are inevitable. Being a teacher is the tough part, he needs to establish the primary tools for his students.
