Reading mulitple result sets from Sybase CT-Lib

I have been looking into allowing the Sybase CT-Lib extension to fetch multiple result sets, and I came across the following comment in php_sybase_ct.c, starting on line 1065: /* Use the first result set or succeed/fail status and discard the * others. Applications really shouldn't be making calls that * return multiple result sets, but if they do then we need to * properly read or cancel them or the connection will become * unusable. */ I'm wondering why the choice was made to go with "cancel them"?
