It's possible. The HD channels are largely on the 110 and 119 sats. which are further to right (west) and lower in the sky than the 101 sat that your dish is now aimed at.
You can get a rough idea whether he might be right by facing in the direction your current dish is facing and looking 18 degrees to the right and a little lower. You can estimate 18 degrees by holding your outspread fingers in front of you at arm's length - the span from the outspread tip of your thumb to the tip of your little finger is about 10 degrees.
