In my opinion, a trust group consists of direct and indirect clients.
I would like to get the correct definition.
Let met give you the two arguments on which I base my understanding:
In the ntp-keygen documentation, I read this sentence:
--Trusted Hosts and Secure Groups
--As described on the Authentication Options page, an NTP secure group
--consists of one or more low-stratum THs as the root from which all other
--group hosts derive synchronization directly or indirectly.
In the stime.pdf documentation , the Figure 13: Trusted certificate (TC)
scheme on page 42 and the Appendix E3 would let me think that indirect
clients are permitted.
I would like to have your understanding.

A trust group consists of one server and its direct clients. So for you
to have one trust group server2 and server3 must be clients of serverT1.

Your current NTP architecture is two trust groups.
The first trust group has serverT1 as its server and server2 as its only
The second trust group has server2 as its server and server3 as its only
