Well yes the alignment might be poor, but the connection not weak? Remember that every classic stem has that "weak" connection as a standard and only connection between handlebar and bike.

Connecting handlebars to a properly supported steerer tube = 1 thing.
Anchoring an unsupported steerer, running through the second headset bearing and connecting handlebars = quite another.
