The "only" part isn't in the documentation :)

 Any placeholder that is immediately followed by "..." [example snipped]
 will match as many times as possible, but at least once. Note that
 this implies that an unconstrained repeated unflagged placeholder (see
 "Placeholder constraints" and "Unflagged placeholders") will consume
 the rest of the command-line, and so should be specified last in the POD.

The only constraint you're providing is 'group.type: string', which is
the default type anyway, so this is effectively unconstrained. After all,
'--hosts' is a string too.

It seems to me this is the intended behaviour rather than a bug, but
please let me know what you think.
