please explain the difference to your allegedly constant 1 .

Simple. Your constant a has a label. The label means that it uses a specific location to store the (constant) value. All refs to the label resolve to the location of the value and hence stringify to the same address.

By contrast 1 has no label. It is an actual literal. This does not require one specific location to store it and therefore refs to it will refer to different locations.
