Change of heart: No.
Change of public face: YES

this is what we can call a manipulation using the social media.
1. you start signalling SegWit and push the percentage up,
2. price goes higher than the initial pump.
3. you dump to take a big profit
4. you go on twitter and say something showing you are doubting your decision and create fear that you may stop at 74.9%
5. when price tanked you buy back with the money+profit
6. you say i changed my mind and will continue signalling!
7. price goes higher and now you have more litecoin than you had in step 1.

and by you i mean F2Pool and the gang of investors who dumped in that big down dive.
