Narrative:
Light transport X on visual approach runway 32 cleared to land. Large transport Y on visual approach runway 23 told to join final approach course on present heading, switched to tower. Large transport Y cut corner by 1 1/2 mi cleared to land runway 23 by tower. Tower controller sent large transport Y around as sep was being lost. Large transport Y reported light transport X in sight and said it did not look like a problem. Tower controller told large transport Y to land 'your discretion.' large transport Y landed approximately 2000' down runway 23 then light transport X rolled through intersection. After tower told large transport Y, 'land your discretion,' large transport Y replied, 'understand cleared to land.' above observed by 2 other ATC specialists not working position and supervisor. Apparently no action taken. Light transport X questioned several times and was told to call tower.
