So as the local base mask has low bits all zero, all addresses within that span will be sequential in memory. But local space is disjoint in global space. This affects only the maximum continuous allocation size and not the total number of allocations.
So I think what you're saying here is that that if turf 10101 has an allocated local address 0000100111, then turf 10100 can't have an allocated local address of 0000000111, because they correspond to the same global address - they'd clash.
