Yes but; we can talk about angles all night long. Look at the attitude in the photo: now consider yourself on the inside sitting in the hot seat on RHS. Looking outside of the front window it must have been exciting and probably looked worse than from three outside. What were the control inputs?
That's what I'm saying... if flare is held for too long, then as the aircraft sinks the pitch attitude can increase 2-3 degrees from normal (to 7-8 degrees ANU) and geometrically reduces the roll clearance.

Note that the seemingly extreme pitch attitude in the original picture could be an "optical illusion", because the camera wasn't held straight & level. Not saying that it is, just that it could be.

Look what happens if we straighten out the picture and measure the fuselage angle vs. the ground:



Now the camera-lens-aircraft geometry is uncertain and I'm not CSI... so the 7.2 degrees could be way off... but one possible hint is to look at the tail section: there's still quite a bit of clearance from the tail to the ground. So maybe the pitch attitude isn't as extreme as the original picture suggests.

Of course pictures do lie so we really can only speculate until the FDR data comes out...
