The tracks didn't actually cross, although from an oblique viewpoint it may have looked as if they did.
The A388 was off the Bovingdon hold, and it turned inside the A321 (off Lambourne) for 27R and 27L, respectively, as mentioned above.
At their point of closest approach (about 200m horizontally) there was around 1800' of vertical separation (give or take - WebTrak rounds heights to 100').
