This is allowed by the Lua spec [1]:
The length of a table t is defined to be any integer index n such that
t[n] is not nil and t[n+1] is nil; moreover, if t[1] is nil, n can be zero.
For a regular array, with non-nil values from 1 to a given n, its length is
exactly that n, the index of its last value. If the array has "holes" (that
is, nil values between other non-nil values), then #t can be any of the
indices that directly precedes a nil value (that is, it may consider any
such nil value as the end of the array).
