Why does my 24-105 have a different magnification (macro ratio) from a 105mm macro lens at same MFD?

Focus breathing.

I noticed that when demonstrating the first 28-200mm that we had for sale.

At 200mm focused to the closest focusing distance it had a similar field of view of a fixed 135mm .

Past about 4-5 metres (I can't remember now) it started to look like a 200mm.
