Well, the U/L bit distinguishes between addresses derived from the globally unique EUI-64 (U bit set) and all other addresses (U bit clear). The ff:fe00 then is our convention to identify addresses derived from 16-bit MAC addresses. There may be other, non-globally-unique addresses in use in a LoWPAN (e.g. for address privacy, SEND, ...), even though that may not be the typical deployment case today.
