You're right, it doesn't apply to buses.
The HGV restriction sign isn't really a weight restriction at all. It's
a vehicle category restriction. Obviously, HGVs, by definition, are
heavy vehicles, but the reasons for imposing the restriction are
generally unrelated to weight. It's more to do with size, congestion,
pollution and impact on other road users. And they're usually
conditional, because the aim is to minimise rather than eliminate HGVs
on the affected roads. In particular, it's typically done to prevent the
roads being used as a through route by HGVs, while still allowing
deliveries to premises within the restriction.
Genuine maximum weight signs, applicable to all vehicles, are rarely
conditional. Those are typically used where there is a safety-related
need to restrict vehicle weight (eg, a weak bridge), so conditional
exceptions would defeat the object.
