Exactly.
If you fly down the LL Corridor VFR, then you have to be 1,000' clear of the congested area. If you go SVFR, then you are absolved of the 1,000' rule, but not the 500' rule or the glide-clear rule. When the corridor limit was 1250', it was impossible to fly the route VFR and not be in breach of the 1,000' rule.
And that was the whole point of the corridor.
