Actually, you'll find that there's a problem when any two VLANs share a
trunk link. A very simple technique to get around this problem is to use
redundant links. Typically Spanning Tree Protocol would disable the second
link, but an administrator could tune the STP parameters so that traffic
from VLAN A could pass over link A - link B would be blocked. Traffic from
VLAN B could pass over link B - link A would be blocked. Oh the joys of
per-VLAN Spanning Tree.
