Simple holy mastery question

[Kaffeefilter]

Hey fellas,
i was wondering how overwriting of the mastery-caused hot (echo of light) works.
Example: I cast a PoH and place a strong echo of light on the group. Then, i cast a circle of healing.
Question: Is the strong echo of light from PoH beeing overwritten by the CoH´s echo of light? Or is it only overwritten if the total CoH-echo is healing for more in total than the remaining PoH-echo ?
