I don't think there are two types of possession. They were speculating there could be, and this is why Fuchs urged Macready to have everyone eat only out of cans, but they didn't really know. I thought for years that Norris was one of those gradual takeovers -- that he had gotten exposed to a few cells and they started taking over his original cells at a geometric rate. And I figured that when he collapsed, that was the point when he lost enough of himself to "die" as the Thing continued to assimilate his body. However Carpenter and others involved in the production have gone on record that Norris had a heart condition, and when the Thing copied him, it did so perfectly, down to the last cell, which means it replicated Norris' heart defect and had a very human heart attack (which couldn't actually kill it, of course, just made that temporary human copy unviable so it had to change).
The problem is, if the Thing can take people over gradually, needing only a small amount of its own cells to start the assimilation process, then there is simply no rational explanation whatever for its using the violent attack method. If it could take people over gradually, without their even knowing until it was too late, why attack some people violently and alarm the survivors into fighting back? It would make no sense. It could just expose everyone a few cells at a time, and sit back and wait for them all to change.
