Why would embryos have different abnormalities than those found in the parent, but still on the same chromosomes?

Let's say we have a male with infertility issues. Him and his wife get a Chromosomal Analysis that comes back with his wife being fine, but him having:

"balanced reciprocal translocation between chromosomes one and ten"

46,XY,t(1;10)(q21;q25.2)

And the embryos from their first IVF round have the following abnormalities:

45,XY,dup(1)(q23q44),del(10)(q26),-22

46,XY,del(1)(q23),dup(10)(q26q26)

Why would the embryos have duplications and deletions on the same chromosome but at different locations than the abnormalities in the potential father?
