If His teaching is interpreted to mean something against the word of YHWH which came before, then that interpretation is flat wrong - simple as that. The only other option is that He is teaching falsely, and therefore cannot be the Messiah, and cannot be known to be the 'maker of the universe.'
The problem with 'precept upon precept, line upon line' is that the thing said before MUST carry more weight than the thing said later, as the previous word is already uttered, and YHWH does not change.It is the same problem as the Pharisee's laws making the immutable Law of YHWH to be made null. His word will not come back to Him empty. This is unique to YHWH among all the pretender 'gods' and proves He is the I AM.
I will not be quick to throw that away.
