Yes, that is because the libc resolver consults /etc/hosts without doing
a DNS lookup.

The standalone dnsmasq (i.e., the dnsmasq that runs when the dnsmasq
package is installed) does consult /etc/hosts when resolving names.
This feature can be disabled.

That's true.

That would be highly unusual. Ubuntu is not unusual in this respect. In
Ubuntu 12.04 /etc/nsswitch contains
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
thus for host name lookups the libc resolver looks first at /etc/hosts.
Try this yourself. Add the line
1.2.3.4 foo
to /etc/hosts and then try "ping foo".
$ ping foo
PING foo (1.2.3.4) 56(84) bytes of data.
^C
