It does sound credible that this type of agreement was made, as it is common to have such concessions made in place of actually contacting the authorities and filing formal charges. This is also way we have the latent lawsuits and charges filed by adults 20+ years later. The parents would concede to these condidtions for the sake of the ministry, organization, family, etc. without being aware of the harm still being done to their child.
It is also common practice with churches, SDA in particular, to move pastors once they offend in one way or the other(spousal abuse, adultery, embezzlement, etc).
Another thing is, I can't think of any other reason why TS needed to commute to 3ABN, when I am sure his brother could have arranged housing for him at 3ABN.
