When you listen to it, note the great contrast between Skitt's 'caught' and
Markus's 'caught' ([kOt]) and the strong similarity of Skitt's 'caught'
to Markus's 'cart' ([kA:t]).
Note also that the first vowel in Skitt's 'bother' doesn't sound at all
like the one in Markus's 'bother' (['bA.D@]), but it does sound quite
similar to the one in Markus's 'father' (['fA:D@]) and 'cart'.
(Markus's pronunciation of 'father' is rather rapid, but it's the
best I could find. I think the vowel sound is still discernible
