Even if all possible sequences of digits occur in Pi, the fact that a particular sequence occurs at a particular position can be "interesting". If nothing else, it would make for a pretty strange compression algorithm (although probably not a practical one for most input data, given how large the indices are likely to be.)

On the average, the index of where in pi a certain sequence occurs, is as long as the sequence itself, thus the average savings of this compression-scheme is zero.
