I actually think it means they decide to no make go further with the LCA. Like they decided to finally not hire the employee or the employee decided to not work for this company anymore.
Actually that makes more sense. It is possible to be working on another visa while a company files the LCA for you (TN, L, visas, etc), but it's probably less likely than a new H1-B hire.
They probably misfiled the LCA at 1m and re filed at 100k.
