That's also called interlocking grain. Most trees grow with some degree of twist or spiral like a candy cane, not perfectly straight. Most of the time the tree grows it's whole life with the spiral going in one direction. Sometimes though the direction of the spiral reverses, so a tree may start out growing with a clockwise twist for 20 years, then suddenly switch to counter-clockwise twist for the next twenty, then switch back or grow straight for a while. Unfortunately when you get tearout like that in a dense tropical wood if often goes a lot deeper than it looks like on the surface and takes a lot of sanding to get rid of. Tough to tell, the first pic looks bad but the next ones not so bad. I would think if LMI is selling radiused boards that are supposed to be nearly ready to use they would not leave tearout like that.
