I think the screw, which runs ahead of the cutting flutes, split the board just as if you were screwing in a screw of that size without drilling a pilot hole, because, in essence, you were.

Picklehead is exactly right. The screw started the split since it was going into virgin uncut wood, and with that small split, the large flutes finished the job.

so would a pilot hole for the screw make a difference?

They are typically used by electricians to drill holes in construction lumber to run romex and plumbers running pipe. The nail chipper aspect of the bit is an improvement over regular self feed bits as they can be damaged or destroyed when hitting nails. These bits aren’t designed for making nice neat holes, they’re designed for speed. The angle of the taper and pitch of the thread of the self feeding screw is designed for use in pine and douglas fir in mind.

Forstner bit if you want a nice hole, hole saw if you don’t care how ragged the hole is.

If you don’t need the nail chipper feature, the regular wood owl bits with cutting spurs on the end cut an extremely nice hole. Especially if you stop just as the lead screw comes out the other side of the wood, turn it over and come in from the other side.

But to answer your second question, yes, a pilot hole makes all the difference to keep an auger bit from splitting wood. Make sure it’s a little smaller than the thickest part of the lead screw and you’ll be good.
