It's not a NLF. This sealing counters people who can casually teleport to a dimension transcendent to them. Going by the Mega-Composite continuity, that's the Crack of Time. Demigra, who is at least 2-C, teleported to the CoT, an enclosed dimension separate and transcendent to space-time, which is 10 to 11-D. The CoT itself is likely 1-B here, and at most, Demigra prior to dimensionally travelling to it was High 1-C.

Despite all that, he was still trapped in the CoT when he was sealed there.
