It's only contradictory if you think of it like the final or
output state, which it is not.

Think of it like the state of an _input_ switch instead.

Like, if we were talking about a light circuit:

[mains switch] - [light switch] - [light bulb]
open/closed open/closed on/off

The breakpoint enablement is like the mains switch's state.

The location's enablement is like the light switch's state.

Open any of the switches, and the light turns off.

There's no equivalent for light on/off (the final state).
