They are different.  But this has always been the case:

$ ./bin/accumulo shell --fake -u root -p ''

Shell - Apache Accumulo Interactive Shell
- version: 1.6.0-SNAPSHOT
- instance name: fake
- instance id: mock-instance-id
- type 'help' for a list of available commands
root@fake> setauths a,b
root@fake> createtable t
root@fake t> insert -l a&b a b c d
root@fake t> insert -l b&a a b c d
root@fake t> insert -l (b)&a a b c d
root@fake t> scan
a b:c [(b)&a]    d
a b:c [a&b]    d
a b:c [b&a]    d
