As long as that host is up, it will tell all other nodes about each
others IP addresses. Normally, that will cause traffic between those
other nodes to go directly between them, not via the host with dyndns.
The only problem is when the dyndns host goes down, and if all other
nodes only have a ConnectTo that host, then they won't be able to see
each other anymore. A simple solution is to set up dyndns for a few
nodes, and add ConnectTo statements to those nodes.

If you really don't like setting up dyndns on more nodes, then you could
also write a host-up script that records the most recently seen
addresses of nodes. An example of such a script can be found here:

In tinc 1.1, there is the AutoConnect feature which replaces manual
ConnectTo statements.
