What happens with dig +trace is subtle, and not always what you want. https://kb.isc.org/article/AA-00208 It's a limitation of the dig tool not being a fully-featured recursive server with a temporary working cache (for intermediate results). Far better to run your own iterative a non-recursive digs if you really want to see what's happening.
