Notice with the line about Tom and Huck being boys, the bottom-up description sounds unnatural.

Since the original Pascal was implemented with a one-pass compiler, the language believes strongly in declaration before use. In particular, procedures and functions must be declared (body and all) before they are used. The result is that a typical Pascal program reads from the bottom up - all the procedures and functions are displayed before any of the code that calls them, at all levels. This is essentially opposite to the order in which the functions are designed and used.
Worth noting that almost every C program is impaired by a similar limitation in the C language (despite the disclaimer that follows this passage about the use of the preproccessor), and many programmers' thought processes suffer because of it—no consideration for the presentability of code (even when not in languages that are affected by this limitation!)
