BIRD 2.x and arrays

Using "[ 192.168.60.0/24+ ]” works, however from the documentation I read the following regarding the `include` operator: 

	Special operators include (~, !~) for "is (not) element of a set" operation - it can be used on […] on prefix and prefix (returning true if first prefix is more specific than second one)

In my case I have "import where net ~ [ 192.168.60.0/24 ] ;”, which should be true because prefix 192.168.60.10/32 is more specific than 192.168.60.0/24. That statement, in fact, is true on Bird 1.6.x. and, without the array ("import where net ~ 192.168.60.0/24 ;”), on Bird 2.0.x. 
Why do my networks get filtered out then? 

Thanks, 
Carlo
