The chromoly could be weaker if it is too thin. It all depends on how it is made. Any frame can break no matter what it is made of if you try hard enough.
You're right in theory. In real life pretty much every chromoly frame is better than high ten.
I don't think theres any chromoly frames out there that are too thin and therefore weaker than hi-ten(both are steel by the way). You aren't getting added strength from hi-ten. Chromoly allows them to make frames that are lighter AND stronger.
