AC21 180 days問題 - 移民

請問一下
如果原本485/140是用EB2 file且已經Pending 180天
但在同公司降級到EB3而file新的140
那可以用這新EB3 140跳槽到其他公司嗎

還是要新的EB3 140 "approve"後滿180天?
我原本以為AC21是只要485 pending 180天及140 approve就可以跳. AC21 180天條款是跟
著485

但根據below說如換employment based category後180天clock要reset, 不知是否正確?
有高手知道嗎 感謝

If an employment-based applicant requests to transfer the
adjustment application to a different employment-based category based on
a new Form I-140, the applicant may not utilize the portability provisions,
if applicable, until 180 days or more after making the transfer request.
The applicant旧 new job offer must be in the same or similar occupational
classification as the job for which the petition was initially filed.
In essence, transferring the basis of the adjustment application resets the
adjudication clock for purposes of portability eligibility
