法華義疏 3.349

3.349

後文明人異於前人，是故知二人異也。又前文判凡失，非佛弟子、非阿羅漢辟支佛，故知是凡夫失也。後文判失，直云是增上慢也。其既是羅漢，不得非佛弟子及非羅漢，但自謂究竟不志求佛，故與其增上慢名也。

The later text clarifies that the person is different from the earlier person; therefore it is known that the two persons are distinct. Furthermore, the earlier text judged the ordinary loss as 'not a disciple of the Buddha, not an arhat, not a pratyekabuddha'; thus it is known to be the loss of an ordinary person. The later text judges the loss by simply saying that they are 'of overweening pride'. Since they are already arhats, they cannot be 'not disciples of the Buddha' and 'not arhats'; it is merely because they claim of themselves that it is ultimate and do not aspire to seek Buddhahood that they are given the name of 'overweening pride'.
