In that case, yeah I agree. The "pants" are typically the same inner diameter as the insulated conductors' outer diameter on each leg, so the connectors would be too large.
The image I posted above is a 'pant' or 'boot' on twin 8 gauge conductors. The connector outer diameter happened to be about the same size for each insulated lead. That's why the heat shrink fit so smoothly over both the boot and the connector. If the boot was large enough to fit over the connector's shell, then the boot would not be a snug fit over the wire insulation within that boot.
As of this posting, I've seen no boots or cable pants with a "boot cut" flare at the ends.
