This is representative of Motobu udundi as taught by Uehara sensei and practiced by dojo in the Motobu-ryu organization, which also includes Motobu kenpo dojo practicing the style passed down by Motobu Choki. Generally, the two styles are pretty distinct as dojo don't mix training in the two styles, but sometimes there are opportunities to cross-train.
I don't know so much about Motobu kenpo, but the Motobu-ryu site
has info on similarities between the two systems, including: me-oto-te kamae, use of taisabaki and counterattacks rather than blocks, and basis in one fundamental form (mutudi/motode for udundi, naihanchi for Motobu kenpo).
Apparently, Choyu sensei and Choki sensei studied toudi together as children and took part in enbu together even as adults, so they must have developed some similarities even though only Choyu sensei is said to have received full instruction in udundi from their father.
