Seems it is cleaner to write it like this:

--8<---------------cut here---------------start------------->8---
    (if (and (re-search-backward crm-separator nil t)
             ;; Matches end of prompt (:) when sep is ":".
             (not (field-at-pos (point))))
        (1+ (point))
      (minibuffer-prompt-end))
--8<---------------cut here---------------end--------------->8---

Have a look.

Here a test to reproduce:

--8<---------------cut here---------------start------------->8---
    (defun crm-init-test-environ ()
      "Set up some variables for testing."
      (interactive)
      (setq my-prompt "Prompt: ")
      (setq my-table
            '(("hi") ("there") ("man") ("may") ("mouth") ("ma")
              ("a") ("ab") ("abc") ("abd") ("abf") ("zab") ("acb")
              ("da") ("dab") ("dabc") ("dabd") ("dabf") ("dzab") ("dacb")
              ("fda") ("fdab") ("fdabc") ("fdabd") ("fdabf") ("fdzab") ("fdacb")
              ("gda") ("gdab") ("gdabc") ("gdabd") ("gdabf") ("gdzab") ("gdacb"))))
    (crm-init-test-environ)

    (let ((crm-separator "[ \t]*:[ \t]*")) 
      (completing-read-multiple my-prompt my-table))
--8<---------------cut here---------------end--------------->8---
