No, I think the debug log disproves this.  The second call does not find
its attributes in the cache, and goes to fetch a different property ID.

Actually, the 2nd Fields is an IList object which contains a list of
TDFields.  I'm not 100% sure what the interface to an IList is, but you
might try ["BUG"] instead of ("BUG").
