Much less confusing like this:
Before "was" was "was", was "was" "is"?
EDIT: To answer your question, all of the words in quotes would be nouns, and the other "wases" are past tense connectives
He has it labeled correctly; it's a statement, not a question. The middle parts are verbs, and the ones flanking on either side are nouns:
Before "was" was "was", "was" was "is".
Before "was" became "was", "was" used to be "is".
