Which they could also do if there was no patent to begin with. If you want different outcomes for different patents, then the point from the original comment will not help. If you think some patent blocks everyone from implementing a good idea, then you would prefer the patent being filled early without a working implementation so that it is closer to expiring when you can actually implement it. For a patent that you consider a bad idea and that no one should be able to implement on the other hand you would prefer that there has to be a working implementation so that it blocks everyone else as long as possible from also implementing it.
