How does a change of route excess affect the validity period?

Say, I buy a Chester-Stockport anytime day return with route "via Altrincham" for £14.60 and pay the appropriate amount to excess the outward part to route "any permitted".

There is no "any permitted" anytime day return, so this would use the cost of an off peak return (£18.60). Based on what some people have said, this would cost £2 (COT 13.2 seems to say something else, but I don't know how to resolve this).

Having done this, I would still have two questions:

When will the outward part expire, assuming that I don't use the return part before this happens?
When will the return part {which I haven't changed) expire?

This process won't change the expiry date of the ticket, as the outbound half of an off-peak return is for use on day of issue (the usual corner cases around necessary overnight breaks of journey notwithstanding) and if you have not excessed the return half of the ticket, its expiry date remains unchanged.

Thanks. I thought that was how it worked. I thought I should check, though, with there being so much about how change of route excess tickets work which isn't on any of the industry web sites.

I wouldn't really want to be in a situation where I was still using the outward part of a return after the return part has expired, of course.
