01 2 3 41 5is a sound advice.
0 stands for a single letter, other digits represent each a string of 2 letters, not necessarily disjoint.
Try to recover the original phrase.

Misunderstanding by Steve Herman)
I think this means that
1->AB
2->BC
is fine
in other words if you thing of each number as a 2-element set of letters, the numbers are not necessarily pair-wise disjoint.
