^^^^ yes this is my understanding.

Here's the quote from the Manual of Information (aka "Green Book")

Vacancies in Quota
When a woman negates her signed Membership Recruitment Acceptance
Agreement and refuses to accept her matched bid at the conclusion of
membership recruitment and does not participate in a ribbon or formal New
Member Ceremony, this space in the chapter’s pledge Quota was not filled.
Therefore, the chapter may immediately bid and pledge another woman,
even if the chapter is over Total. However, if the chapter has received quota
additions, the chapter may only pledge additional women to the established
pledge quota and not to the quota plus quota additions. Example: If quota is 25
and a chapter receives quota (25) plus 2 quota additions for a total of 27 new
members and three new members do not accept their bids the chapter may
pledge 1 new member to fill to quota of 25.
