Yes, I am familiar with it, that's why the metaphor feels forced to me.
We can postulate that there has been a single, original form of Bassai/Passai; a kind of Ur-Passai, if you will. However, the differences in execution of those three styles that are in the OP are close to negligible, because they are interpreting the sequence of the same clearly identifiable transmission of the form, namely that of Matsumura to Itosu. The transmission from Itosu to Funakoshi (Shotokan) and Mabuni (Shito-ryu) and eventually Ohtsuka (Wado-ryu, via both Funakoshi and Itosu) is very well documented.
More Rosetta Stone-ish would have been to compare, say, the Matsumura, Matsumora ad Tachimura versions that are clearly the same form but have significant differences in both execution and details. Another more sensible option would have been to put Tawada, Ishimine and Itosu versions side by side as they are versions of the slightly more ancient Passai of Matsumura himself.
