The first `replace-regexp-in-string' has to be applied to the return
value of the second one. IOW they have to be nested.

Also, you need to double again backslashes in replacement string, or use
a non-nil LITERAL argument in `replace-regexp-in-string'.

Eventually, I made a typo in my suggestion: the second line should be:

  (org-export-derived-backend-p backend 'latex)

In a nutshell:

  (defun my-personal-table-continuation-strings (row backend info)
    (when (org-export-derived-backend-p backend 'latex)
      (replace-regexp-in-string
       "multicolumn{[0-9]+}{l}{\\(.*\\)}" "\\ldots\\ continued from previous 
page"
       (replace-regexp-in-string
        "multicolumn{[0-9]+}{r}{\\(.*\\)}" "continued on next page \\ldots"
        row nil t 1) nil t 1)))
