In other words, what is the execute bit used for?

The execute bit is used differently for directories than for files. For files, the execute bit determines who can run it as a program. For directories, it determines who can access that directory.
To answer your question, yes a program can read and write any file with a permission of 0##6 (leading "0" designates Octal Notation. "#" can be any octal number). However, if it was in a directory with permissions that are any even number (which is what happens when the execute bit for "other" is not set to 1), you're going to have problems...
