The author make a mess of different concepts. If I remember well, memory storage in IBM 3x0 and PDP/Vax for strings were done in the same order, from left to right. Binary data was different. the famous and old distinction between "little endian" and "big endian" way of ordering the bytes from left or right when storing a word in memory, from a register. See http://en.wikipedia.org/wiki/Endian
Other important differences were the basic unit of I/O in records, of fixed size in IBM (normally of multiple of 80 bytes, the size of an IBM/Hollerith punched card), and variable size in DEC world, perhaps from its use of paper tape.
