X25519 multiplication step 1 result.
Step 1 of X25519 multiplication is to compute the product of two X25519 unsigned 258-bit integers.
Both multiplication inputs are limited to 258 bits, and so the product will have at most 516 bits.

Raw product.
Big integer multiplication produces a result with a number of elements equal to the sum of the number of elements in each input.

Partition into low-order and high-order bits.
Reduction modulo p requires separating the low-order 256 bits from the remaining high-order bits.
Since the value will never exceed 516 bits (see above), there will be at most 260 high-order bits.
