Yes, the base bar hold is more like riding on the drops rather than on the hoods.
Personally I think I'd prefer to have my base bar in a position analogous to my hoods, but then I use the base bar for (a) comfort (occasionally sitting up on long rides... I obviously need better adaptation) and (b) on climbs which are less likely to be an important consideration in TTs.
