I just got off the phone with my sifu and we both agreed on something in regards to our 5 Animal Form. Lau Bun most likely choy lee Fut-itized this form from its original Northern elements since he was strictly a southern gung fu guy all of his life. Sifu said we don't know what it originally looked like as lau bun was taught it. so over the years if it had any northern flavor it doesn't anymore its CLF now.
we also talked about how Si Mo Yuen was already an elderly woman she may have just walked lau bun through the form. and since lau bun was pro southern style he just practiced it with the same hung sing flavor as his hung sing CLF.
still, people wont' be able to find another form with the exact same sequences from another school or system. the framework of this form is very distinct and even when like jakes videos the form is modified, we can tell where and how.
