The two-deep leadership principle means that an adult should never be in the presence of a youth without another adult present. That is, at least two adults when interacting with youth.
In the BSA, you may be allowed to have two or more youth with one adult for temporary periods of time if circumstances require it, such as transportation or skills instruction. In such cases, the group should stay within public view.
I imagine most people don't worry about this issue with home teaching, but if a parent is uncomfortable with the arrangement, I'm not going to begrudge him that. Protecting youth is serious business.
With home teaching, however, the only time in which the two-deep principle could be violated is during transport. Presumably, there would be an adult present at the home teaching appointment. None of the options to reconcile this are very convenient, but they might include
a) the young man's parent drives him to the appointment
b) the adult enlists another adult (spouse or otherwise) to accompany the drive to the home teaching appointment.
c) each young man is assigned to home teach with two adult leaders
d) two young men are assigned in a companionship with an adult
As it stands right now, the young man's parents bear the bulk of the burden of ensuring that the young man doesn't come in harm's way, as he would only be able to go home teaching with their permission. I don't know of any precedent to state that while home teaching, youth are in the care of the Church in the same way they are at young men activities (speaking about liability, anyway). If the legal liability were to change, you'd probably see more guidelines from the Church about it*.
* That being said, priesthood leaders should not be assigning young men to home teach with men whose records have been annotated.
