 In the first case, the user has four single quotes on a line, wishfully hoping that the shell will match them up as outer quotes around a string with literal single quotes:
 
-                        v--------match--------v
+    #                   v--------match--------v
     alias server_uptime='ssh $host 'uptime -p''
-                                   ^--match--^  
+    #                              ^--match--^  
 
 The shell, meanwhile, always terminates single quoted strings at the first possible single quote:
 
-                        v---match--v
+    #                   v---match--v
     alias server_uptime='ssh $host 'uptime -p''
-                                             ^^
+    #                                        ^^
 
 Which is the same thing as `alias server_uptime='ssh $host uptime' -p`.
 
 There is no way to nest single quotes. However, single quotes can be placed literally in double quotes, so we can instead concatenate a single quoted string and a double quoted string:
 
-                        v--match---v
+    #                   v--match---v
     alias server_uptime='ssh $host '"'uptime -p'"
-                                    ^---match---^
+    #                               ^---match---^
 
 This results in an alias with embedded single quotes.
