Because you're in the negative territory. The standard way of scaling the volume knob is to have 0 at the end (aka your reference level). Anything below will be negative. It doesn't get "lower". It just gets closer to 0 as you increase the volume. -25dB is higher than -30dB, not lower.
Think of it this way: At 0 volume, you are at your max/reference volume level. -30dB means you're 30dB away from max. When you increase the volume to -25dB, you are now only 25dB away from max.
(yes, I know it'll go past 0, too, but you may encounter harmful distortion/clipping there).
