session start hook for C TS API

In the server_push example plugin, the plugin attaches to the session
start hook globally.  But the handling of the session hook event is
this:

  case TS_EVENT_HTTP_SSN_START:
    ssnp = (TSHttpSsn)edata;
    TSHttpSsnHookAdd(ssnp, TS_HTTP_TXN_START_HOOK, contp);
    TSHttpSsnReenable(ssnp, TS_EVENT_HTTP_CONTINUE);
    break;

What's the advantage of doing it like this, rather than attaching
globally to the transaction start hook?
