I saw this as follows:
transition 1, you either got the right adress or not
1 : 2 3 4 5

transition 2, given that you got the right adress, someone
is either there or not
2 3 : 4 5

transition 3, given that nobody is not at home, that could
be because of short absense or long absense
2 : 3

transition 4, given that somebody is at home, that
person can either participate or not
4 : 5

If you don't care about the difference between short
absense and long absens ("both are deadways in comparison
with being at home") then you can combine them. If you
combine them, then you'll need to do so in your variable,
you cannot just leave transition three out without

This is not a difference between -seqlogit- and -logit-,
actually there can be none, instead the difference is due
to the fact that in one you included interaction terms and in
the other you did not.

Hope this helps,
