SYSML17 — BindingConnector ends multiplicity

The semantics of the Binding Connector is described as follow :

“8.3.2.10 Binding Connector

Description

A Binding Connector is a connector which specifies that the properties at both ends of the connector have equal values. If the properties at the ends of a binding connector are typed by a DataType or ValueType, the connector specifies that the instances of the properties must hold equal values, recursively through any nested properties within the connected properties. If the properties at the ends of a binding connector are typed by a Block, the connector specifies that the instances of the properties must refer to the same block instance.”

So, I understand that definition if the multiplicity of the properties linked by the binding connector is 0..1 or 1. But what happen is the upper bound of the multiplicity is greater than 1? If for example, it is 0..* ? And moreover, what happen when the multiplicity of both property is different, as for example on one end 0..1 and on the other end 1 ? In this case, as according to the previous definition, the value of both properties has to be equal, what happen to the value of the proiperty which multiplicity is 1 when the other property is not yet defined?
