<ProfileIdentifier> has a ModellingRule ManatoryPlaceholder which means a node with BrowseName <ProfileIdentifier> NEVER appears on instance so the proposed fix is wrong.

Technically a new Node with some undetermined BrowseName should appear on every instance but if this is to occur a "Sample" node needs to be explicitly stated in the specification where an instance of ConnectionPointType is defined.

From a practical perspective, the modelling rule should be OptionalPlaceholder. We could have more philosophical discussions on what the point of ManatoryPlaceholder is given this unexpected side effect.
