You put the emphasis on the wrong part of the quoted documentation. The essential part is has ever been used in a numeric context. Either side of binary + is classifies as numeric context.
The more technical reason is "you get normal increment if the SV isn't a PV". As you can see, the variable does change by just looking at it.
