I'm commish of a Yahoo league and my guess is if it was done via computer, he may have made the change but not "save changes". I've been guilty of this myself and always double check that the change did happen
Yahoo fixed that really stupid problem this year. Using the default/superior method, lineup (starting/bench) changes are instantly saved. The second you move somebody, they are there. There's none of this moving them...and then having to submit or save change...crap.
But agree with the above ^, the phone app seems buggy. An awful lot of people have reported doing something on the phone, only to have it not show up. I haven't had that problem, nor has my wife (I don't use the phone much, but she does)...but a lot of other people have claimed too. Far too many claims for it to be false.
