While the orbital inclinations of the two satellites are very close, the altitudes are not. Because the X-37B is in a lower orbit it is moving faster.
It is currently quite far ahead of the space lab and moving farther from it. This is all pointed out in the article in the OP.
Perigee height: 329 km
Apogee height: 340 km
Perigee height: 352 km
Apogee height: 366 km
