It seems like DHCP servers do figure out subnets connected to the client. However, having 2 logical subnets on the same segment still will have problems. Options would be to group clients using user class option in dhcp.conf. This, however, assumes that the client is configurable to send user class along with the DHCP request/discover message. You will need to check if this is feasible in your current clients. If you've static/known users, simple option is to group by MAC.
