Bert looked at this and discounted it for two reasons:
1. Side clearance is typically 10x - 35x larger than these values. If these were side clearance values, the engine wouldn't last.
2. The S63TU engine and other BMW engines also list these specs but add the word "Radial" to them. For S63TU, it's very clearly bearing clearance specs as the wording is consistent across many BMW engines. Here's the link:

Still being concerned with the odd wording, Bert checked with Indy and NASCAR engine builder friends. Both confirmed it meant rod bearing clearance; side clearance was therefore excluded.
