Explicit Initialization gets value from exactly one Scalar Flow
Scalar Flow supplies value for zero, one or many Explicit Initialization
The initial value is supplied by a Scalar Flow. This means that the value must be a single scalar value.
A given Scalar Flow may or may not supply an attribute initialization value and the same Scalar Flow can flow into more than one Explicit Initialization.
