I understand that this is true for the ABMC implementation. My goal with making this vague is
to not have this reset set in stone if some other implementation behaves differently.

In the docs "mbm_total_bytes" and "mbm_local_bytes" are termed "events" ... maybe
"The MBM events (mbm_total_bytes and/or mbm_local_bytes) associated 
counters may reset when mbm_assign_mode is changed."?
