Not entirely: the trunk (between switch and FreeBSD) will have the two different vlan tag id's, and you cannot differentiate between the two by doing 'normal' IP aliasing (yet done with ifconfig). The physical interface won't get an IP address at all, but the two virtual vlan interfaces will. You can/must keep the two networks apart with a firewall (pf for instance).
