I would like to suggest another, IMO more usable definition of sa:

check the single word to the right of sa, and remove words leftward until the same word has been removed.

thus: "ti cmalu xunre nixlu ckule sa xunre nanla ckule" is equivalent to:
"ti cmalu xunre nanla ckule"

(a multi sumti bridi with the following word of selma'o LO would be a better example)

what do you think?
