Can a single 802.11 card interface multiple networks simultaneously?

Picture the following setup:

Two 802.11-equipped computers. They form an ad-hoc local wireless
network without a common access point. The first does not need, and
will not be, connected to the Internet. The second will be though,
through an external access point.

The question is, can the second computer's 802.11 card interface both
the local ad-hoc network and the external network simultaneously, or
would two 802.11 cards be required for this?

The first computer can implement Internet connection sharing and then it
would potentially work. Look at this

Two separate wifi networks are required. That usually means two separate
client adapters. Some dual-band trimode adapters may be able to support an
802.11g or 802.11b network concurrently with an 802.11a network
