If there was some crud in there, you most likely saw them slowly grinding through it with greased threads..backing off and going back in further a few times. I've done exactly this literally dozens of times. In my experience modern Shimano bottom brackets can be a bit of a tight fit compared to the ease with which we used to screw in old cup-and-cone assemblies. Regardless of the instructions to fit one side all the way in, then the other, I find that sometimes I have to back the first side halfway out a bit, then work the other side, then back to the first. And I've had different levels of install effort on the same frame with different cartridge BBs.
If you really want to get your hands dirty and put your mind at ease, get yourself a crank-bolt wrench, crank puller, BB tool, and an adjustable wrench (or socket wrench); bring up the install page at parktool.com so you know which side turns which; and start removing both cups a bit. You'll probably find that they pull out and go back in straight, but with some effort. This should ease your mind that's it's in there..and you'll know how to replace it!
