Necessity of all three MD-Compliant padding conditions
For Merkle-Damgård hashing, MD-compliant padding is defined as any padding scheme satisfying:
$M$ is a prefix of $\text{Pad}(M)$
$|M_1|=|M_2|\Rightarrow |\text{Pad}(M_1)|=|\text{Pad}(M_2)|$
$|M_1|\neq … I can see how different length messages having the last padding block could lead to collisions, for example. …
