That is the point of the word repeatedly in the post you quoted.

The fact it went to the Titanic 10 times is essentially why it failed the 11th time - every time you go down it basically flexes the assembly which weakens it; this time it presumably developed a small crack which explosively expanded resulting in the decompression.

Looks like the titanium end caps separated from the interface ring (the part that is glued/bonded to the carbon fibre hull). Can't see any carbon fiber from the still attached to that interface ring, must have absolutely shattered into a million shards.
