No, but in this context, there is no difference.
You are getting a copy of the data on the real roots. You are NOT
creating the data.

Slow connections tend to be due to bad reverse look ups.
Are you going to be auth for all of the in-addr.arpa zones?
And most DNS lookups do NOT involve the root servers.

If there is a problem with resolving the PTR record, it is usually
because they have misconfigured it, not because of a query to root.

A response NEVER came? Did you get a timeout message?
What was the query?
