The doc clearly says:

"There is no particular restriction on the numbering,
e.g. you can have several groups with the same number in which case
the last one to match (i.e. the rightmost match) will win."

There is no mention of an automatic assignment. It says the last one
will win, so assigning a number which is already used for 
a previous group should work.
