Ok, now that 2 people posted screenshots it's clear why some people are getting the 7 dms and some people are just getting 6, it's because of the bruise glitch like I mentioned, every version has it so it doesn't matter which one you use.
You can see in Milk's screenshot that on frame 367 the chest piece is slightly bruised, while on Zal's screenshot it isn't. This happens because of the use of Shift+P (or simillar).
When you go through a replay by using Shift+P you can see that the joints you bruise will stay bruised for as long as you keep on pressing Shift+P, and the effect isn't just visual, the joints will actually be easier to dismember.
Knowing this one can assume Zal paused the replay very few frames before the hit and then edited it, hence the chest not being bruised, while Milk paused a bit earlier, went to frame 367 by using Shift+P (or simillar) and this way some bruise remained from Jaker's hand touching Uke's chest before the grab.
That bit of bruise is enough to make the extra dm as you can also see here:
Even so, my opinion is still that this should be a record since I'm pretty positive the bruise glitch was used in other records such as beznick's full dm (I'm not sure about this example though).
