bash doesn't like nested single quotes, even with escapes. So the first \'
gave you a literal backslash and ended the quoted part, then the second \'
gave you a literal ' and continued without quoting. The final ' would then
open a new quoted string, but bash doesn't get that far because it sees the
(now unquoted) parentheses and tries to parse them as a command expansion.

Note that it thinks it's still in a quoted string and wants me to continue.
