Voila pourtant la partie de la doc de bash qui explique cette fonctionalite. 
Il s'agit bien de DUPLICATION et pas de redirection.

Duplicating File Descriptors

 The redirection operator 

 [n]<&word 

 is used to duplicate input file descriptors. If word expands to one or more 
digits, the file descriptor denoted by n is made to be a copy of that file 
descriptor. If the digits in word do not specify a file descriptor open for 
input, a redirection error occurs. If word evaluates to -, file descriptor n 
is closed. If n is not specified, the standard input (file descriptor 0) is 
used. 

 The operator 

 [n]>&word 

 is used similarly to duplicate output file descriptors. If n is not 
specified, the standard output (file descriptor 1) is used. If the digits in 
word do not specify a file descriptor open for output, a redirection error 
occurs. As a special case, if n is omitted, and word does not expand to one 
or more digits, the standard output and standard error are redirected as 
described previously.
