Yes it does.  What makes you think it doesn't?

All the commands issued from a "root shell" (that is, a shell running
with UID 0) will also run with UID 0, unless the command itself drops
privileges.  Examples of commands that drop privileges are su, sudo,
and setuidgid.

# id
uid=0(root) gid=3(sys) 
groups=0(root),1(other),2(bin),4(adm),5(daemon),6(mail),7(lp),20(users)
# echo "$(id)"
uid=0(root) gid=3(sys) 
groups=0(root),1(other),2(bin),4(adm),5(daemon),6(mail),7(lp),20(users)

It's the same.
