What does "CLR Thread 0x25e @RDI" mean?

This is the output of the !refs -target 000000951d7df438

SOSEX command. I interpret it as "RDI register on CLR stream 0x25e is 000000951d7df438". However, an examination of the dump does not support this claim.

Note:

As you can see, in the last command, I am looking at the output of the command r

run across all threads. No register in any stream matters000000951d7df438

So I don't understand what it means CLR Thread 0x25e @ RDI

. What does it mean?
