Yeah. A contemporary double chainring is ramped and pinned, in order to be more simply shifted from one ring to the next. To put it simply, the chainring "wishes" to go off the chain to another cog. Without a derailleur to help keep it set up, the lateral pull with the chain shifting over the rear, combined with some highway jostling, can make the chain tumble off the entrance.
