It's _can_bypass_approvers :-)

The corresponding code in _can_bypass_approvers explains why we short-circuit in both cases:

>         /* If the best handler that still exists bypasses approval, then
>          * we're going to bypass approval.
>          *
>          * Also, because handlers are sorted with the best ones first, and
>          * handlers with BypassApproval are "better", we can be sure that if
>          * we've found a handler that still exists and does not bypass
>          * approval, no handler bypasses approval. */

However, the second sentence does not apply to BypassObservers - the value of BypassObservers does not affect a Handler's "quality" score (although perhaps it should - see Bug #30043).

So, it should only short-circuit in the TRUE case:

    gboolean bypass = [...];

    DEBUG (...);

    if (bypass)
      return TRUE;
