Not if you connect only one computer at a time. Otherwise you are right.

Btw. you could also achieve the second topology (star) if you let the
desktop "emulate" a switch. This can be done with bridgeing: a virtual
network dev is defined with an IP address in the same subnet as modem
and laptop (the real network devs have no IP). All iincoming traffic
from eth0 is passed to eth1 and vice verse. (Simplified)
