Judging from the source code[1] in the author's repository, it is the latter. (what I see is: perform 96 instructions, then subtract 64 from the message length, and repeat until the message length is 0)

Intel seems to be the same way [2](2013) - i.e. looping over multiple instructions per 64 byte block.

Interesting, thanks for pointing that out.

This code is such a good example of the potential value of formal verification tools for crypto primitives.
