「若爾應識至非皆是觸」者，毘婆沙師難。若前後相生者，應第二念觸時識非皆有受，以此念觸生後念受故。第三念受同時諸識，亦應非皆是觸，以此念受從前念觸生故。

Regarding "If so, consciousness should … not all are contact": the master of the Vibhāṣā objects. If they produce one another sequentially, then at the time of contact in the second moment, consciousness should not all possess feeling, because contact in this moment produces feeling in the subsequent moment. The consciousnesses simultaneous with feeling in the third moment should also not all be contact, because feeling in this moment arises from contact in the prior moment.
