It's been decades since my last jump

)), and I am not really qualified.
My understanding is that one lands on bottom toe pick but immediately sequences to the whole blade for flow- out and shock absorption, with a flexible knee bent acting as a shock absorber, as well. If the toe pick is jammed into the ice at a too wide of an angle the flow out is compromised, and there's nothing to soften the impact of landing. Also, that might mean that the body is out of alignment, which, combined with a hard hit, makes for a stronger jolt; more dangerous for ankle, knee and hip.
Now if somebody corrected me or elaborated I would be grateful.
